Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an integrated air conditioner and its control method. Background Technology

[0002] With the development of air conditioning technology, the traditional functions of household air conditioners have gradually evolved from simple cooling and heating to multi-functional integration. However, existing integrated air conditioners still have functional limitations and technical defects, especially in humidification. Most integrated air conditioners on the market currently lack a dedicated humidification module, resulting in the ineffective utilization of condensate and defrost water generated during operation, leading to water waste. While some air conditioners have humidification functions, they generally use a separate spray humidification device at the air outlet. Although this design provides faster humidification, uneven spray distribution can cause user discomfort, and the nozzle structure is prone to clogging, requiring regular maintenance. Furthermore, the dense spray can cause dampness around the air outlet. In addition, some air conditioners use a perforated design at the air outlet for spray humidification, but this structure, being directly connected to the indoor air duct, not only causes air leakage affecting cooling and heating efficiency but also increases energy consumption due to structural defects. These problems severely restrict the performance improvement of air conditioning products and the user experience, and there is an urgent need for a new technical solution that can achieve uniform humidification, effectively utilize condensate water, and not affect the basic performance of air conditioning to solve the many shortcomings of existing technologies. Summary of the Invention

[0003] The embodiments of the present invention provide an integrated air conditioner and its control method, which aims to solve the problems of uneven humidification and air leakage in the humidification module of existing integrated air conditioners.

[0004] This invention provides an integrated air conditioner, comprising:

[0005] A duct assembly includes a fan and a duct casing. The fan is disposed inside the duct casing, which surrounds the outer periphery of the fan. The beginning and end of the duct casing are not closed to form an open duct outlet.

[0006] The humidification component is at least partially located at the air outlet of the air duct;

[0007] A water supply component, with its water outlet facing the humidification component, is used to supply water to the humidification component.

[0008] Furthermore, the humidification assembly includes a drive unit, a roller, and a roller shutter humidification belt. The axis of the roller is parallel to the axis of the fan. The roller shutter humidification belt is wound around the roller. The drive unit drives the roller to rotate to unfold or rewind the roller shutter humidification belt.

[0009] Furthermore, in the height direction, the end of the air duct volute is higher than the beginning of the air duct volute, the roller is at the same height as the end of the air duct volute, and the roller is located above the beginning of the air duct volute in the height direction; wherein, when the roller shutter humidifying belt is unfolded, the roller shutter humidifying belt extends downward from the roller in the height direction and connects to the beginning of the air duct volute, and the air outlet of the air duct is defined between the roller and the end of the air duct volute.

[0010] Furthermore, a drainage channel extending along the axial direction of the fan is provided on the end wall of the beginning of the duct volute.

[0011] Furthermore, the drainage channel includes two water-blocking walls spaced apart and a sloping groove located between the two water-blocking walls. The sloping groove has a high end and a low end at both ends along the axial direction of the fan, and a drainage outlet is provided on the low end.

[0012] Furthermore, the humidifying belt of the roller shutter is provided with a first magnetic attractor on the side away from the roller, and the drainage channel is provided with a second magnetic attractor, and the first magnetic attractor and the second magnetic attractor are magnetically attracted to each other.

[0013] Furthermore, the humidifying belt of the roller shutter is an electrically heated belt.

[0014] Furthermore, the water supply assembly includes a chassis, an inlet component, an outlet component, a pump, and a storage component. One end of the inlet component is connected to the water collection area on the chassis, and the other end of the inlet component is connected to the inlet of the storage component. The pump is mounted on the storage component. One end of the outlet component is connected to the outlet of the storage component, and the other end of the outlet component extends above the reel.

[0015] Furthermore, the integrated air conditioner also includes a water level detection sensor, which is located in the water collection area on the chassis.

[0016] In a second aspect, the present invention also provides a control method for an integrated air conditioner, comprising the integrated air conditioner described in the first aspect, the method comprising:

[0017] Determine whether the air conditioner is in humidification mode;

[0018] If the air conditioner is in humidification mode, the control drive unit drives the roller to rotate forward to unfold the roller shutter humidification belt;

[0019] If the air conditioner is not in humidification mode, the control drive unit drives the roller to reverse so as to fold the roller shutter humidification belt.

[0020] This invention provides an integrated air conditioner and its control method. The integrated air conditioner includes an air duct assembly, a humidification assembly, and a water supply assembly. The air duct assembly consists of a fan and an air duct casing. The fan is disposed inside the air duct casing, which is arranged around the outer periphery of the fan and forms an open air duct outlet between its beginning and end. The humidification assembly is at least partially disposed at the air duct outlet. The water outlet of the water supply assembly is arranged corresponding to the humidification assembly to supply water to it. This invention, by placing at least a portion of the humidification component at the air outlet of the air duct component, combined with the precise water supply from the water supply component to the humidification component and the open design of the air outlet, allows the air conditioner to humidify simultaneously while cooling and heating, solving the problem of missing or insufficient humidification modules in traditional integrated air conditioners and improving indoor air humidity comfort. On the other hand, it provides a structural basis for the efficient use of condensate and defrost water to avoid water waste, and also avoids the problems of uneven humidification, nozzle blockage, damp ground, and reduced efficiency caused by traditional spray or hole humidification, ensuring stable air conditioning performance and optimizing the user experience.

[0033] As people's demands for indoor environmental comfort increase, humidification functionality in integrated air conditioners is gradually becoming a key focus for users, in addition to meeting basic cooling and heating needs. However, existing integrated air conditioners still have significant shortcomings in humidification. Some products lack an effective humidification module, making it difficult to meet users' humidity requirements. Even products equipped with humidification modules have significant design flaws, with uneven humidification and air leakage being particularly prominent. These issues not only affect the user experience but may also reduce the core performance of the air conditioner. Therefore, solving the problems of uneven humidification and air leakage in the humidification modules of existing integrated air conditioners has become an important direction for the technological improvement of integrated air conditioners. To this end, this application proposes a novel integrated air conditioner and its control method to address the problems of uneven humidification and air leakage in the humidification modules of existing integrated air conditioners.

[0034] Please see Figures 1 to 7 , Figure 1An integrated air conditioner according to an embodiment of the present invention includes: an air duct assembly 1, a humidification assembly 2, and a water supply assembly 3. The air duct assembly 1 includes a fan 11 and an air duct casing 12. The fan 11 is disposed inside the air duct casing 12, and the air duct casing 12 is arranged around the outer periphery of the fan 11. The beginning end 121 and the end end 122 of the air duct casing 12 are not closed to form an open air duct outlet 123. The humidification assembly 2 is at least partially disposed at the air duct outlet 123. The water supply assembly 3 has its water outlet facing the humidification assembly 2 and is used to supply water to the humidification assembly 2.

[0035] Reference Figure 1 and Figure 2Specifically, a modular air conditioner, also known as a window air conditioner, has its evaporator and condenser housed in the same casing. This embodiment of the modular air conditioner comprises three core components: a duct assembly 1, a humidification assembly 2, and a water supply assembly 3. These components work together to provide the basic airflow delivery function and the additional humidification function of the air conditioner. The duct assembly 1 provides a channel for airflow, the humidification assembly 2 humidifies the airflow output from the duct assembly 1, and the water supply assembly 3 provides the necessary water source for the humidification operation of the humidification assembly 2. The duct assembly 1 includes a fan 11 and a duct casing 12. The fan 11 can be a centrifugal fan 11, a cross-flow fan 11, or an axial fan 11, or other common air conditioner fan types. Its structure can be flexibly designed according to the internal installation space of the modular air conditioner, for example, a cylindrical structure. Its core function is to drive airflow to form air conditioning ventilation. The duct volute 12 is a shell structure with a receiving cavity. Its material can be high-strength plastic, metal or composite material. The overall shape is an arc or spiral contour adapted to the outer periphery of the fan 11. The beginning end 121 and the end end 122 of the duct volute 12 are not closed to form an open duct outlet 123. The specific forms of the non-closed arrangement may include, but are not limited to: maintaining a preset interval between the end face of the beginning end 121 and the end face of the end end 122 of the duct volute 12; forming an arc-shaped notch during the extension of the beginning end 121 and the end end 122 of the duct volute 12; bending the beginning end 121 and the end end 122 of the duct volute 12 in different directions to form an opening. The specific position of the duct outlet 123 can be set on the side, top or bottom of the duct volute 12 according to the air outlet requirements of the air conditioner. Its shape can be rectangular, circular or irregular. Its core function is to allow the airflow in the duct assembly 1 to be output to the outside. In this embodiment, the duct housing 12 has a general "C"-shaped structure, with its open air outlet 123 located on the top and side of the duct housing 12. The fan 11 and the duct assembly 1 are configured as follows: the fan 11 is coaxially or eccentrically positioned within the receiving cavity of the duct housing 12, and the duct housing 12 surrounds the outer periphery of the fan 11, forming a channel for airflow between the outer wall of the fan 11 and the inner wall of the duct housing 12. When the fan 11 is started, air can enter the duct housing 12 and flow along the channel between the fan 11 and the duct housing 12, finally exiting from the air outlet 123.The humidifying component 2 is at least partially located at the air outlet 123 of the air duct. Its specific structural form may include, but is not limited to, a roller shutter-type humidifying strip (made of water-absorbing material and may be long and narrow), a honeycomb-shaped humidifying net (made of porous water-absorbing material and having honeycomb-shaped through holes), and a sheet-shaped humidifying cotton (made of flexible water-absorbing material and may be rectangular or irregularly shaped). The roller shutter-type humidifying strip may be partially located in the internal space of the air outlet 123 or partially cover the outer cross-section of the air outlet 123. The honeycomb-shaped humidifying net may be partially embedded in the edge of the air outlet 123 or partially snapped onto the inner wall of the air outlet 123. The sheet-shaped humidifying cotton may be partially attached to the air outlet end face of the air outlet 123 or partially suspended inside the air outlet 123. The core function of the humidifying component 2 is to absorb water and contact it with the airflow output by the air duct component 1 to humidify the airflow. In short, the humidifying component 2 may have various different structural forms, which are not limited here. The positional relationship between the humidification component 2 and the air duct component 1 is as follows: at least a part of the structure of the humidification component 2 is located on the airflow path of the air outlet 123 of the air duct, so that the airflow output from the air outlet 123 can flow directly through the humidification component 2, providing conditions for the airflow to contact and humidify with the humidification component 2. The water supply component 3 is used to supply water to the humidification component 2. Its specific structural form may include, but is not limited to, an independent water supply structure consisting of a water storage tank and a water supply pipe (the water storage tank is used to store water, and the water supply pipe connects the water storage tank and the humidification component 2); a recycling water supply structure consisting of a water collection area 311 of the chassis 31, a water pump 34, and a water supply pipe (the water collection area 311 of the chassis 31 is used to collect condensate or defrost water generated by the air conditioner, the water pump 34 is used to extract water from the water collection area 311, and the water supply pipe delivers the water to the humidification component 2); and an external water supply structure consisting of an external water source interface, a solenoid valve, and a water supply pipe (the external water source interface connects to an external water source, the solenoid valve controls the water supply, and the water supply pipe delivers the water to the humidification component 2). The water outlet of the water supply component 3 may be set as a pipe opening, a spray head, or a drip nozzle, etc. Its core function is to stably deliver water to the humidification component 2. The water outlet of the water supply component 3 is positioned towards the humidification component 2, specifically towards the top, middle, or upper part of the humidification component 2, so that the water output from the water supply component 3 can drip, spray, or be guided directly onto the humidification component 2, ensuring that the humidification component 2 can continuously obtain water to maintain the humidification function.

[0036] Traditional integrated air conditioners with humidification functions often use independent spray humidification at the air outlet, which can easily lead to uneven humidification, nozzle clogging, and dampness on the ground near the air outlet. Some air conditioners have holes drilled in the air outlet to achieve humidification, which can cause air leakage due to connection with the indoor air duct, reducing the air conditioner's cooling or heating capacity. In this embodiment, the humidification component 2 is at least partially located at the air outlet 123 of the air duct, eliminating the need for additional holes in the air outlet and structurally avoiding air leakage problems caused by such holes. At the same time, the water supply component 3 accurately supplies water to the humidification component 2, and the humidification component 2 directly contacts the airflow output from the air outlet 123. As the airflow flows through the humidification component 2, it can carry moisture evenly, avoiding the unevenness and nozzle clogging problems of traditional spray humidification, and preventing dampness on the ground due to dense spray. In addition, by setting up the humidification component 2 and the water supply component 3, the integrated air conditioner is supplemented with a humidification function, solving the problem of the lack of a humidification module. Therefore, the integrated air conditioner of this embodiment of the invention, firstly, enables the basic functions of cooling and heating (i.e., airflow driven by the fan 11, which is then output from the air outlet 123 after heat exchange in the air conditioning heat exchange system) to be achieved simultaneously through the cooperation of the humidification component 2 and the water supply component 3, thus meeting the user's demand for indoor air humidity; secondly, it eliminates the need for additional holes to be drilled in the air duct component 1 or the air conditioner casing to install the humidification structure, avoiding air leakage problems caused by drilling holes, ensuring the stability of the air conditioning's cooling or heating capacity, and preventing a decrease in air conditioning performance; thirdly, the humidification component 2 directly contacts the airflow at the air outlet 123 for humidification, which, compared to traditional spray humidification methods, allows for more direct contact between the airflow and the humidification component. The humidifier 2 has more thorough contact, resulting in a more uniform humidification effect. It also eliminates the need for nozzles, avoiding maintenance issues such as nozzle clogging and damp ground caused by dense spray. Fourth, the water supply component 3 provides a structural basis for utilizing water resources such as condensate and defrost water generated during the operation of the air conditioner. This water resource can be collected through the water supply component 3 and transported to the humidifier 2, which is conducive to the recycling of water resources and reduces water waste. Fifth, the structural design of each component is highly flexible. Depending on the specific model of the integrated air conditioner, internal space, and usage requirements, the appropriate type of fan 11, the structure of the air duct casing 12, the form of the humidifier component 2, and the form of the water supply component 3 can be selected, making it widely applicable.

[0037] Reference Figure 3In one embodiment, the humidification assembly 2 includes a drive component 21, a roller 22, and a roller shutter humidification belt 23. The axial direction of the roller 22 is parallel to the axial direction of the fan 11. The roller shutter humidification belt 23 is wound around the roller 22. The drive component 21 drives the roller 22 to rotate to unfold or rewind the roller shutter humidification belt 23. Specifically, the drive component 21 of the humidification assembly 2 can be a common drive structure such as a micro motor, stepper motor, or servo motor. The motor housing can be cylindrical, square, or other shapes adapted to the internal space of the air conditioner. Its core function is to output rotational power to drive the roller 22 to move. The engagement between the drive component 21 and the roller 22 can be achieved in various ways. For example, the output shaft of the drive component 21 can be directly connected to one end of the roller 22 via a coupling, or the output shaft of the drive component 21 can be meshed with the end of the roller 22 via a gear transmission mechanism. The installation position of the drive component 21 can be set on the outer side of one end of the roller 22, the side wall of the air duct volute 12, or the bracket of the air conditioner housing, depending on the internal layout of the air conditioner. It is only necessary to ensure that it can stably drive the roller 22 to rotate. The roller 22 is a rod-shaped structure with a preset length. Its material can be a metal rod, a high-strength plastic rod, or a composite material rod. The cross-sectional shape can be circular. Bearings or bushings can be set at both ends of the roller 22 to improve rotational stability. The axis of the roller 22 is parallel to the axis of the fan 11. The installation position of the roller 22 must be adapted to the structure of the air outlet 123 of the air duct. For example, it can be fixed to the top, side wall, or edge of the air outlet 123 of the air duct housing 12 by a bracket. The roller 22 must cooperate with the roller humidification belt 23 in the humidification assembly 2. Its length must not be less than the width of the roller humidification belt 23 after it is unfolded to ensure that the roller humidification belt 23 can be stably rolled up on it. The roller humidification belt 23 is a rollable strip structure. Its material can be water-absorbing cotton, fiber woven belt, or composite water-absorbing material belt. The surface can be provided with uniformly distributed micropores to improve the water absorption and humidification effect. The width of the roller humidification belt 23 must be adapted to the length of the roller 22, and the length must meet the requirement that it can at least partially cover the air outlet 123 of the air duct after it is unfolded. One end of the roller shutter humidifying strip 23 is fixedly connected to the outer peripheral wall of the roller 22, and can be fixed by means of adhesive, snap-fit, or sewing. When the roller 22 rotates forward under the drive of the drive component 21, the roller shutter humidifying strip 23 can gradually unfold along the outer periphery of the roller 22. When the roller 22 rotates in reverse, the roller shutter humidifying strip 23 can be rolled up and stored along the outer periphery of the roller 22. The roller shutter humidifying strip 23 is unfolded and rolled up by driving the roller 22 through the drive component 21, so that the humidifying component 2 can flexibly adjust the state of the roller shutter humidifying strip 23 according to the usage requirements, avoiding the problem that the fixed humidification structure is difficult to adapt to different air outlet scenarios.In addition, this embodiment achieves several technical effects. First, the automatic unfolding and rewinding of the roller shutter humidifying belt 23 is achieved through the cooperation of the drive component 21 and the roller 22, eliminating the need for manual operation and improving ease of use. Second, the roller shutter humidifying belt 23 reduces space occupation when rewinding, adapting to the limited space inside an integrated air conditioner. When unfolded, the area covering the air outlet 123 of the air duct can be adjusted according to needs, balancing humidification effect and air output efficiency. Third, the parallel arrangement of the roller 22 axis with the fan 11 axis allows the roller shutter humidifying belt 23 to better conform to the airflow direction of the air outlet 123 after unfolding, improving the uniformity of contact between the airflow and the humidifying belt and further optimizing the humidification effect.

[0038] Reference Figure 4In one embodiment, the end 122 of the duct volute 12 is higher than the beginning 121 of the duct volute 12 in the height direction. The roller 22 is at the same height as the end 122 of the duct volute 12 and is located above the beginning 121 of the duct volute 12 in the height direction. When the roller humidifying belt 23 is unfolded, the roller humidifying belt 23 extends downward from the roller 22 in the height direction and connects to the beginning 121 of the duct volute 12. The duct outlet 123 is defined between the roller 22 and the end 122 of the duct volute 12. Specifically, the duct volute 12 of this embodiment has an overall shape resembling a "C"-shaped shell structure. The material can be high-strength plastic, metal, or composite material. The two ends of the "C"-shaped structure form the beginning 121 and the end 122 of the duct volute 12, respectively. In the height direction, the end 122 of the duct volute 12 is higher than the beginning 121, so that the duct volute 12 extends in a "C" shape. Its inner sidewall can be designed as a smooth arc surface according to the airflow requirements to reduce airflow resistance. Its core function is to cooperate with the fan 11 to form an airflow channel and form an open duct outlet 123 through the non-closed characteristics of its own "C"-shaped structure. The duct outlet 123 specifically includes the area adjacent to the top and side of the duct volute 12, providing a path for airflow output. The roller 22 is a rod-shaped component adapted to the "C"-shaped structure of the duct housing 12 and the position of the duct outlet 123. It can be made of metal, high-strength plastic, or composite materials, and its cross-sectional shape can be circular. Its length must match the width of the top area of ​​the duct housing 12. It is used for winding the roller humidification belt 23, and under the drive of the drive unit 21, it enables the roller humidification belt 23 to unfold and rewind. The positional relationship between the roller 22 and the duct housing 12 is as follows: the roller 22 is at the same height as the end 122 of the duct housing 12, and the roller 22 is positioned above the beginning 121 of the duct housing 12 in the height direction. Specifically, it can be fixed to the side wall of the end 122 of the duct housing 12 or to a fixed structure inside the air conditioner via a bracket. Simultaneously, the duct outlet 123 defined between the roller 22 and the end 122 of the duct housing 12 corresponds to the top area of ​​the duct housing 12, ensuring stable airflow output from this top area. The roller shutter humidification belt 23 is a strip structure that can be unfolded along the height direction. The material can be water-absorbing cotton, fiber woven belt or composite water-absorbing material belt. The surface can be provided with uniform micropores to improve the water absorption and humidification effect. Its length must meet the requirement of extending from the roller 22 downward along the height direction to the beginning 121 of the air duct volute 12, and its width must be adapted to the width of the side area of ​​the air duct volute 12.One end of the roller shutter humidifying belt 23 is fixedly connected to the outer peripheral wall of the roller 22 (it can be fixed by means of adhesive, snap-fit, etc.). When the roller 22 rotates forward and unfolds the roller shutter humidifying belt 23 under the drive of the drive component 21, the roller shutter humidifying belt 23 can extend downward from the roller 22 along the height direction and connect with the beginning end 121 of the air duct volute 12 (the connection method can include magnetic attraction, snap-fit, hook connection, etc.). At this time, the roller shutter humidifying belt 23 can cover the side area of ​​the air duct volute 12. Combined with the top air duct outlet 123 defined by the roller 22 and the end 122 of the air duct volute 12, the entire air duct outlet section is covered (only the top area is reserved as the air duct outlet 123 for air outlet). By defining the "C"-shaped structure of the duct housing 12 and the height relationship between the beginning end 121 and the end end 122, the equal height position of the roller 22 and the end end 122 of the duct housing 12 and the height position relative to the beginning end 121 are clearly defined. At the same time, the humidification belt 23 is defined to cover the side area and the top area of ​​the duct housing 12 after it is unfolded, which is the air outlet 123 of the duct. This ensures that the humidification belt 23 can completely cover the entire duct outlet section and avoid uneven humidification caused by improper positioning. In addition, this embodiment achieves several technical effects. First, by clarifying the height and positional relationship of each component, the rolled-up humidifying belt 23 can accurately cover the cross-section of the air duct outlet (leaving only the top air outlet) after unfolding, ensuring that the airflow can fully contact the rolled-up humidifying belt 23 when flowing through the air duct outlet 123, thus improving the uniformity of humidification. Second, the design of the "C"-shaped structure of the air duct volute 12 and the rolled-up humidifying belt 23 not only ensures the effective air outlet area of ​​the air duct outlet 123, but also avoids the problem of traditional humidification structures occupying too much air outlet space, balancing air outlet efficiency and humidification effect. Third, the positional adaptation between the roller 22 and the end 122 of the air duct volute 12 allows the airflow of the air duct outlet 123 (top area) to flow stably through the rolled-up humidifying belt 23 covering the side area, further enhancing the contact effect between the airflow and the humidifying belt and improving the overall humidification performance.

[0039] Reference Figure 5In one embodiment, a drainage channel 1221 extending axially along the fan 11 is provided on the end wall of the starting end 121 of the duct housing 12. Specifically, the starting end 121 of the duct housing 12 is the lower part of its "C"-shaped structure, and the end wall of the starting end 121 is a vertically or inclined wall structure, made of the same material as the main body of the duct housing 12, such as high-strength plastic or metal. The drainage channel 1221 extending axially along the fan 11 is provided on this end wall. The drainage channel 1221 can be elongated, with its length adapted to the axial length of the fan 11, its width designed according to drainage requirements, and its depth sufficient to accommodate water flow. Its function is to collect water dripping from the roller shutter humidification belt 23, preventing water from entering the duct or other components of the air conditioner. The channel is located in the upper part of the end wall of the starting end 121, directly below the lower end of the rolled-up humidifying belt 23 after it is unfolded, ensuring that water dripping from the rolled-up humidifying belt 23 can fall directly into the channel. This solves the problem of water dripping from the rolled-up humidifying belt 23 after use, which can easily lead to dampness in the air duct or damage to components. It effectively collects excess water after humidification, prevents water splashing from affecting the internal environment of the air conditioner, and ensures stable operation of the equipment.

[0040] Continue to refer to Figure 5 In this embodiment, the drainage channel 1221 includes two spaced-apart water-retaining walls 1221a and a sloping groove 1221b located between the two water-retaining walls 1221a. The sloping groove 1221b has a high end and a low end formed at both ends along the axial direction of the fan 11, and a drain outlet 1221c is provided on the low end. Specifically, the drainage channel 1221 includes two water-retaining walls 1221a and a sloping groove 1221b. The water-retaining walls 1221a are plate-shaped structures extending along the axial direction of the fan 11, and the material can be the same as the channel. The two water-retaining walls 1221a are spaced-apart to form the two side boundaries of the channel, which are used to prevent water from overflowing from both sides of the channel. The sloping groove 1221b is located between two water-retaining walls 1221a. The bottom of the groove is inclined, with a high end and a low end along the axial direction of the fan 11. The low end has a drain outlet 1221c, which can be circular or square. It can be connected to a drain pipe or directly to the water collection area 311 of the air conditioner chassis 31 through the guide structure on the duct casing 12. After the water flows into the groove, it flows from the high end to the low end along the slope and is finally discharged through the drain outlet 1221c. This solves the problem of poor drainage and water accumulation in the drainage channel 1221. Thus, the sloping design accelerates water discharge, prevents water accumulation in the groove from breeding mold, improves drainage efficiency, and improves air quality.

[0041] Reference Figure 2 and Figure 5In one embodiment, a first magnetic attractor 24 is provided on the side of the roller shutter humidifying belt 23 away from the roller spool 22, and a second magnetic attractor is provided on the drainage channel 1221. The first magnetic attractor 24 and the second magnetic attractor are magnetically attracted to each other. Specifically, the first magnetic attractor 24 is located on the side of the roller shutter humidifying belt 23 away from the roller spool 22, and can be a permanent magnet or an electromagnet. It can be long and strip-shaped or block-shaped, and is fixed to the lower edge of the humidifying belt by adhesive or snap-fit. The second magnetic attractor (not shown in the figure) is located in the drainage channel 1221, and can be installed on the end wall of the channel or the top of the water-blocking wall 1221a. Its material is compatible with the first magnetic attractor 24 to ensure that the two can be magnetically attracted to each other. After the roller shutter humidifying belt 23 is unfolded, the first magnetic attractor 24 at its lower end and the second magnetic attractor of the drainage channel 1221 are precisely attracted to each other, thereby fixing the humidifying belt to the channel. This solves the problem of unstable connection and easy displacement of the roller shutter humidification belt 23 after it is unfolded. The magnetic fixation ensures that the humidification belt stably covers the side area of ​​the air duct, avoids airflow disturbance causing the humidification belt to shift, and ensures humidification uniformity and structural stability.

[0042] In one embodiment, the roller shutter humidifying strip 23 is an electric heating strip. Specifically, the roller shutter humidifying strip 23 in this embodiment is an electric heating strip. The structure of the electric heating strip may include a base layer, a heating layer, and a protective layer. The base layer is a rollable strip carrier, and the material can be heat-resistant and has a certain degree of flexibility, such as plastic or fiber cloth. The heating layer can use heating wire, heating film, or carbon fiber heating elements, which are uniformly embedded or attached to the base layer and can generate heat after being energized. The protective layer is wrapped around the outside of the heating layer and can be made of insulating, heat-resistant, and breathable materials, which ensures electrical safety and does not hinder moisture penetration and airflow. The electric heating strip maintains its rollable characteristics and is adapted to the winding and unfolding operation of the roller 22. The electric heating strip is wound on the roller 22, and the driving component 21 can drive the roller 22 to realize its unfolding and winding. The electric heating strip can also be electrically connected to the control circuit of the air conditioner to realize the on / off control of the heating function. This solves the problem that traditional humidifiers can only humidify, have a single function, and are prone to mold growth due to dampness after long-term use. It combines humidification and heating functions. In heating mode, it can help increase the outlet air temperature. After humidification, it can also achieve high-temperature evaporation and cleaning through heating to prevent mold growth, thus expanding the functional dimensions of humidifier component 2.

[0043] Reference Figure 6 and Figure 7In one embodiment, the water supply assembly 3 includes a chassis 31, a water inlet 32, a water outlet 33, a water pump 34, and a water storage unit 35. One end of the water inlet 32 ​​is connected to a water collection area 311 on the chassis 31, and the other end of the water inlet 32 ​​is connected to the water inlet of the water storage unit 35. The water pump 34 is mounted on the water storage unit 35. One end of the water outlet 33 is connected to the water outlet of the water storage unit 35, and the other end of the water outlet 33 extends above the roller 22. Specifically, the water supply assembly 3 includes a chassis 31, a water inlet 32, a water outlet 33, a water pump 34, and a water storage unit 35. The chassis 31 is a disc-shaped structure at the bottom of the air conditioner, with a partial depression forming a water collection area 311 for collecting condensate, defrost water, etc., generated during the operation of the air conditioner. The material can be corrosion-resistant plastic. The water inlet 32 ​​can be a flexible or rigid pipe, with one end connected to the water collection area 311 of the chassis 31 and the other end connected to the water inlet of the water storage component 35, thus transporting water resources to the water storage component 35. The water storage component 35 is a sealed or semi-sealed container, such as a plastic water tank, used to store water resources and supply water to the humidification component 2. A water pump 34 is installed on the water storage component 35 and can be a miniature submersible pump, a self-priming pump, or a vacuum pump, used to extract water from the water storage component 35. The water outlet 33 can be a rigid conduit or a flexible water pipe, with one end connected to the water outlet of the water storage component 35 and the other end extending above the roller 22, with its end 122 equipped with a dripper or a spray nozzle. Specifically, water from the water collection area 311 of the chassis 31 flows into the water storage component 35 through the water inlet 32, and the water pump 34 transports the water in the water storage component 35 to the top of the roller 22 through the water outlet 33, dripping onto the roller humidification belt 23. This solves the problem that traditional water supply methods cannot utilize the water resources generated by the air conditioner itself and rely on external water sources. It enables the recycling and reuse of condensate and defrost water, saves water resources, and the water supply path is adapted to the structure of the humidification component 2 to ensure stable water supply to the humidification belt.

[0044] In this embodiment, the integrated air conditioner also includes a water level detection sensor (not shown in the figure), which is located in the water collection area 311 on the chassis 31. Specifically, the water level detection sensor is a water level detection switch, located in the water collection area 311 of the chassis 31. It can be a float switch, electrode switch, etc., and is fixed to the inner wall of the water collection area 311 by a bracket, and can directly detect the water level height H in the water collection area 311. The water level detection switch is electrically connected to the water pump 34 (e.g., vacuum pump) and control unit in the water supply component 3 to form a linkage control logic. When the water level in the water collection area 311 reaches the first preset value H1, the water level detection switch sends a signal to the control unit to trigger the vacuum pump to start. The vacuum pump extracts air from the water storage component 35 (i.e., the water tank), causing the air pressure in the water tank to drop below the pressure at the water collection area 311. Under the action of the air pressure difference, the water in the water collection area 311 is forced into the water tank through the water inlet 32. When the water level drops to the second preset value H2, the water level detection switch sends a signal again, the control unit responds and shuts down the vacuum pump, wherein the first preset water level H1 is always greater than the second preset water level H2. This solves the problem of water waste or untimely pumping caused by inaccurate water level control in the collection area 311. By setting a preset water level threshold, the vacuum pump is automatically started and stopped, accurately controlling the water level in the collection area 311, avoiding energy waste caused by ineffective vacuum pump operation, and ensuring that the water storage tank can be replenished in a timely manner, guaranteeing a continuous water supply.

[0045] In other embodiments, the water storage component 35 may be equipped with a filtration structure, such as a filter screen or activated carbon filter layer at the water inlet of the water storage component 35, to filter impurities in the condensate and defrost water collected in the water collection area 311 of the chassis 31, preventing impurities from clogging the water outlet 33 or adhering to the roller shutter humidification belt 23 and affecting the humidification effect. The water supply assembly 3 may also include a damper structure, which is located at the channel connecting the water storage component 35 to the outside. When the vacuum pump is started to draw a vacuum, the damper automatically closes under the action of airflow, ensuring that an effective negative pressure environment can be formed inside the water storage component 35 to smoothly draw water. When the vacuum pump is turned off, the damper can automatically open under the action of air pressure balance to maintain the air pressure balance inside and outside the water storage component 35. In addition to being an electrically heated belt, the surface of the roller shutter humidifier belt 23 can also be treated with antibacterial agents, such as adding antibacterial agents or using antibacterial materials, to further inhibit mold growth and improve hygiene. In addition, the control logic can also include the adjustment of the degree of unfolding of the roller shutter humidifier belt 23. For example, according to the indoor humidity requirements, the rotation angle of the roller 22 can be controlled by the drive component 21 to adjust the unfolding length of the roller shutter humidifier belt 23 to adapt to different humidification requirements and enhance the flexibility of humidity regulation of the air conditioner.

[0046] This invention also provides a control method for a modular air conditioner, applied to the modular air conditioner described in the above embodiments. This modular air conditioner has been described in detail in the above embodiments, and for the sake of brevity, it will not be repeated here. The method includes steps S1-S3.

[0047] S1. Determine whether the air conditioner is in humidification mode;

[0048] S2. If the air conditioner is in humidification mode, the control drive 21 drives the roller 22 to rotate forward to unfold the roller humidification belt 23.

[0049] S3. If the air conditioner is not in humidification mode, the control drive 21 drives the roller 22 to reverse so as to fold the roller humidification belt 23.

[0050] Specifically, this control method is applied to the integrated air conditioner of the above embodiment. Its core is to control the unfolding and folding state of the roller shutter humidifying belt 23 in the humidifying component 2 according to the operating mode of the air conditioner. The execution subject of this control method is the control unit of the air conditioner. The control unit can automatically determine whether the operating mode is humidifying mode by receiving mode commands input by the user (such as humidifying mode commands sent through remote control, control panel or smart terminal) or by detecting the indoor humidity by the internal sensors of the air conditioner. When the determination result is that the air conditioner is in humidifying mode, the control unit sends a forward rotation control signal to the drive component 21. After receiving the signal, the drive component 21 (such as micro motor, stepper motor, etc.) drives the roller 22 to rotate in a preset direction, so that the roller shutter humidifying belt 23 wound on the roller 22 gradually unfolds until the roller shutter humidifying belt 23 reaches the preset unfolding position (for example, completely covering the side area of ​​the air duct volute 12 and connecting with the beginning 121 of the air duct volute 12). At this time, the roller shutter humidifying belt 23 is in working state and can cooperate with the water supply component 3 to humidify the airflow output from the air outlet 123 of the air duct. When the judgment result indicates that the air conditioner's operating mode is not humidification mode (such as cooling mode, heating mode without humidification, standby mode, etc.), the control unit sends a reverse control signal to the drive unit 21. After receiving the signal, the drive unit 21 drives the roller 22 to rotate in the opposite direction to the forward rotation direction, so that the unfolded roller humidification belt 23 is gradually rolled up onto the roller 22 until the roller humidification belt 23 is completely retracted, avoiding the roller humidification belt 23 occupying the air duct space or affecting airflow in non-humidification mode. In practical applications, the control unit can determine the operating mode in various ways: for example, when the user manually selects the humidification mode, the control unit directly recognizes the command and determines it to be humidification mode; another example is that the air conditioner is equipped with a humidity sensor, and when the indoor humidity is detected to be lower than the preset humidity threshold, the control unit automatically determines that it needs to enter the humidification mode; yet another example is that in heating mode, if the indoor humidity is detected to be lower than the comfortable humidity range matching the current temperature, the control unit can automatically trigger the humidification mode. The forward and reverse rotation control of the drive unit 21 can be achieved by changing the power supply direction of the motor, and the rotation angle of the roller 22 can be limited by the preset program of the control unit to ensure that the roller humidification belt 23 covers the target area exactly when it is unfolded and is completely stored without being exposed when it is rolled up.

[0051] This embodiment solves the problem of the humidifier component 2 occupying space and affecting the air conditioning's air output efficiency in non-humidification mode. By automatically controlling the unfolding and folding of the roller shutter humidifier belt 23 according to the operating mode, the humidifier component 2 only works when needed and is stored away when not in use. This improves the intelligence of the air conditioner's operation, eliminating the need for manual operation of the humidifier component 2. In non-humidification mode, the roller shutter humidifier belt 23 retracts, reducing obstruction to airflow and ensuring the air output efficiency of the air conditioner's basic cooling and heating functions. It also prevents the roller shutter humidifier belt 23 from accumulating dust due to prolonged exposure to airflow, extending its service life and reducing the frequency of cleaning and maintenance.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
