Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, in particular to an air conditioner. BACKGROUND

[0002] The indoor air is generally dry in autumn and winter, which makes people feel uncomfortable. Especially when the air conditioner is turned on indoors, it accelerates the loss of moisture on people's skin. To alleviate the dry and uncomfortable feeling, a humidifier is usually configured in a general household to heat the indoor air. The humidifier occupies a certain space, and the humidifier is easy to overturn and cause inconvenience.

[0003] In the prior art, an air conditioner with a humidifying function is provided, which integrates the structure of the humidifier in the air conditioner, so that the air conditioner has the functions of adjusting air and humidifying.

[0004] On a conventional cabinet machine, the humidifying method mainly uses a wet film humidification. When in use, the flowing air in the air conditioner passes through the wet film and transports the moisture in the wet film to the indoor, so as to achieve the purpose of humidifying the indoor. However, the humidification process of the wet film needs the wet film to evaporate naturally to generate water vapor, the humidification amount is small, and the user's perception of the humidification effect is not obvious. SUMMARY

[0005] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides an air conditioner, which has a large humidification amount and obvious humidification effect.

[0006] According to the air conditioner of the embodiment of the present application, the air conditioner comprises: a shell, the shell defines an installation cavity in the shell, and the shell is provided with an air outlet; a heat exchange device, the heat exchange device is arranged in the installation cavity; a humidifying device, the humidifying device is arranged in the installation cavity; the humidifying device comprises: a water tank, the water tank is located below the heat exchange device; a steam generator, the steam generator is located above the heat exchange device, and the steam generator has a steam outlet capable of discharging steam to the air outlet; a water pipe, the water pipe is connected to a water outlet of the water tank and a water inlet of the steam generator at two ends respectively; and a water pump, the water pump is used to drive water in the water tank to flow along the water pipe into the steam generator.

[0007] According to the air conditioner of the embodiment of the present application, by arranging the humidifying device, the steam generator takes water from the water tank and generates sufficient water vapor, the sufficient water vapor is discharged from the steam outlet, mixed with the flowing air, and the flowing air mixed with the sufficient water vapor is transported to the indoor, thereby rapidly increasing the air humidity in the indoor and having obvious humidification effect. The water tank of the humidifying device is located below the heat exchange device at a lower position of the air conditioner, which is beneficial to lowering the center of gravity of the air conditioner after the water tank is filled with water, improving the stability of the air conditioner when placed, and also facilitating water replenishment. By arranging the steam generator above the heat exchange device, the water vapor discharge position is high, and when the water vapor is discharged through the air outlet, the discharge range is farther and wider.

[0008] In some embodiments, the steam generator includes: a support box defining a receiving cavity, the support box having partition ribs to divide the receiving cavity into a water inlet cavity, a heating cavity, and an exhaust cavity, the water inlet cavity being connected to the heating cavity through a first communication port, the heating cavity being connected to the exhaust cavity through a second communication port, the water inlet cavity being connected to the water inlet of the steam generator, and the exhaust cavity being connected to the steam outlet of the steam generator; and a heating element for heating the water in the heating cavity.

[0009] The support box's housing is divided into a water inlet chamber, a heating chamber, and an exhaust chamber by partition ribs. Water introduced by the pump flows sequentially through these chambers, while the steam generated during heating is discharged through a steam port connected to the exhaust chamber. The heating chamber allows the heating element to concentrate heat on the water within a short time, thereby accelerating steam generation and reducing humidification waiting time. The water inlet chamber buffers the water volume, preventing a sudden drop in temperature caused by a large influx of low-temperature water into the heating chamber, and ensuring the water remains in a state of continuous heating and evaporation, thus guaranteeing stable humidification. The exhaust chamber helps separate water vapor from hot water, maximizing the amount of steam discharged through the steam port.

[0010] In some embodiments, the humidification device includes a liquid level detector connected to the steam generator and electrically connected to a water pump. The water pump adjusts its operating state based on the detection result of the liquid level detector. This achieves automatic control of the water level within the steam generator, preventing insufficient water in the steam generator from causing dry burning and damage to the heating element, while maintaining the water level within the steam generator within a suitable range.

[0011] Furthermore, the liquid level detector includes: a detection box connected to the support box, the detection box having a float cavity communicating with the receiving cavity; a float element disposed within the float cavity; and a sensing element disposed on the detection box, the sensing element being used to sense the rise and fall of the float element, and the sensing element being electrically connected to the water pump. Thus, by sensing the rise and fall of the float element, the water level in the receiving cavity is determined, a water level detection signal is obtained, and then sent to the water pump to adjust its operating state, thereby realizing automatic water level control in the receiving cavity of the steam generator.

[0012] Furthermore, the float cavity and the receiving cavity are connected by a third connection port and a fourth connection port, the third connection port being configured to be at least partially higher than the highest liquid level in the receiving cavity, and the fourth connection port being configured to be at least partially lower than the lowest liquid level in the receiving cavity.

[0013] Furthermore, the support box is provided with two first connecting pipes on one side adjacent to the exhaust chamber, and the detection box is provided with two second connecting pipes. The first connecting pipes are plugged into and connected to the second connecting pipes, and the two first connecting pipes respectively constitute the third communication port and the fourth communication port.

[0014] Furthermore, the receiving cavity also includes a buffer cavity located between the heating cavity and the exhaust cavity. The upper end of the partition rib is lower than the height of the receiving cavity, so that the tops of the water inlet cavity, heating cavity, and exhaust cavity are connected.

[0015] In some embodiments, the steam generator further includes: an insulation box fitted over the support box; and a protective box fitted over the insulation box. The insulation box reduces heat loss from the support box, improves the efficiency of steam generation, and saves energy. The protective box provides structural support and protection for the insulation box and support box, reducing the risk of damage to the support box from collisions with other components within the mounting cavity.

[0016] Furthermore, the support box includes: a steam tank body, the steam tank body being open at the top and having a mating opening at the bottom, with the partition rib integrally connected inside the steam tank body; a steam tank top cover, the steam tank top cover being connected to the top of the steam tank body; and a steam tank bottom cover, the steam tank bottom cover being connected to the mating opening at the bottom of the steam tank body, with the heating element mounted on the steam tank bottom cover.

[0017] Furthermore, the humidification device includes: a steam pipe, one end of which is connected to the steam port of the steam generator, and the other end of which extends downward to the air outlet or into the air outlet duct of the air conditioner.

[0018] In some embodiments, the air conditioner includes a vertically arranged frame, a water tank fixed to the bottom of the frame, a steam generator fixed to the top of the frame, and a heat exchange device connected to the frame; the frame is connected to the housing by fasteners.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] The following is for reference. Figures 1-10 An air conditioner 100 according to an embodiment of the present invention is described.

[0050] like Figures 1-3As shown, an air conditioner 100 according to an embodiment of the present invention includes: a housing 1, a heat exchange device 2, and a humidification device 3. A mounting cavity 11 is defined within the housing 1, and an air inlet (not shown) and an air outlet 12 are provided on the housing 1. The heat exchange device 2 and the humidification device 3 are disposed within the mounting cavity 11.

[0051] In the present invention, the heat exchange device 2 and the humidification device 3 are vertically arranged inside the casing 1. Part of the humidification device 3 is located above the heat exchange device 2, and part is located below it. This design allows the air conditioner 100 to have a columnar shape, reducing its floor space and facilitating indoor placement. The type of this air conditioner 100 is not limited; it can be a floor-standing unit or a portable air conditioner, etc.

[0052] The humidifying device 3 in this embodiment is used to generate water vapor, thereby enabling the air conditioner 100 to have a humidifying function. Figures 1-2 As shown, the humidification device 3 includes a water tank 4, a steam generator 5, a water pipe 6, and a water pump 7. The water tank 4 is located below the heat exchange device 2, that is, the water tank 4 is located near the bottom of the air conditioner 100. When the air conditioner 100 is a portable air conditioner, the air conditioner 100 has two heat exchange devices 2, and the water tank 4 is located below the two heat exchange devices 2. The steam generator 5 is located above the heat exchange devices 2, and the steam generator 5 has a steam port 51 that can discharge steam to the air outlet 12. The two ends of the water pipe 6 are connected to the water outlet 41 of the water tank 4 and the water inlet 525 of the steam generator 5, respectively. The water pump 7 is used to drive the water in the water tank 4 to flow into the steam generator 5 along the water pipe 6.

[0053] In this embodiment, the humidifier 3, when in use, uses a water pump 7 and a water pipe 6 to transport water from the water tank 4 to the steam generator 5. The steam generator 5 directly generates sufficient water vapor from the incoming water, and the sufficient water vapor is discharged from the steam port 51 and delivered into the room through the air outlet 12. After the water vapor is discharged, it mixes with the air flowing through the heat exchange device 2, and then mixes with the indoor air after entering the room, thereby increasing the indoor humidity.

[0054] The method by which the steam generator 5 produces water vapor is not limited and can be any method known in the prior art. For example, the steam generator 5 heats water to absorb heat and evaporate it into water vapor, or it uses ultrasound to vibrate water molecules and convert them into water vapor. Compared to using a wet curtain to remove water molecules with flowing air, the steam generator 5 of this application generates water vapor more efficiently and quickly, significantly improving the humidification effect of the air conditioner. In some solutions, the humidification capacity of the steam generator 5 can reach 800-1500 ml / h, with a noticeable humidification effect that improves user comfort.

[0055] In this application, as Figure 1As shown, placing the water tank 4 below the heat exchange device 2 and the steam generator 5 above the heat exchange device 2 has many advantages.

[0056] First, the water tank 4 of the humidifier 3 needs to be replenished frequently. The water tank 4 is located below the heat exchanger 2, which is a low position and makes it easy to replenish water. Moreover, the water tank 4 is relatively heavy when full. Placing the water tank 4 below the heat exchanger 2 can lower the center of gravity of the air conditioner 100 and improve the stability of the air conditioner 100 when placed.

[0057] Furthermore, water may spill out when disassembling or refilling the water tank 4. This application positions the water tank 4 below the heat exchanger 2. If water spills from the water tank 4, the water flow will not reach the heat exchanger 2, reducing the likelihood of water accumulation and mold growth on the heat exchanger 2. When the air conditioner 100 has a water tank 4 installed, the electrical control components within the air conditioner 100 can be positioned above the water tank 4, avoiding the risk of short circuits caused by water spilling onto the electrical control components.

[0058] The steam generator 5 is positioned above the heat exchange device 2. The steam generator 5 can easily have its steam outlet 51 located above the air outlet 12 of the air conditioner 100 for exhaust. This high steam discharge position allows for a wider and farther exhaust range when discharged through the air outlet 12. Especially since the air conditioner 100 of this application is typically installed vertically indoors, the air outlet 12 is relatively close to the ground. When furniture or appliances are placed on the floor, they can obstruct the airflow. By setting the steam discharge position high, the likelihood of the steam encountering obstacles in its path is reduced, allowing it to travel a greater distance smoothly. This also enables the steam to mix more effectively with more indoor air, improving the uniformity of indoor air humidification.

[0059] In this application, by separating the water tank 4 and the steam generator 5, the internal space of the casing 1 can be fully utilized, making it easier to plan and fill the humidification device 3 after the internal components of the casing 1 are arranged, which is beneficial to improving the compactness of the internal structure of the air conditioner 100.

[0060] Understandably, when the air conditioner 100 is in use, a large amount of airflow passes through the heat exchanger 2 for heat exchange. During this heat exchange, the airflow also compresses the heat exchanger 2, causing it to vibrate. Therefore, in a typical air conditioner 100, the heat exchanger 2 is assembled with high precision and installed securely to reduce vibration during airflow. In this application, by placing the water tank 4 and the steam generator 5 at the upper and lower ends of the heat exchanger 2 respectively, instead of placing them inside the heat exchanger 2, assembly interference with the heat exchanger 2 is reduced, and the assembly difficulty of the humidification device 3 is also lowered.

[0061] Furthermore, the water tank 4 and the steam generator 5 are positioned to avoid the heat exchange device 2. When air enters the air conditioner 100 and blows through the heat exchange device 2, it does not need to pass through the water tank 4 and the steam generator 5, which also reduces air resistance and noise, and prevents the water tank 4 and the steam generator 5 from shaking due to wind after being filled with water.

[0062] In this application, the heat exchange device 2 includes an indoor heat exchanger 21 and a heat exchanger bracket 22. The indoor heat exchanger 21 is used to connect to the compressor (not shown) of the air conditioner 100. The compressor drives refrigerant to flow into the indoor heat exchanger 21. The flowing refrigerant exchanges heat with the air flowing through the indoor heat exchanger 21, thereby cooling or heating the air. The heat exchanger bracket 22 is used to install and fix the indoor heat exchanger 21. The shapes of the indoor heat exchanger 21 and the heat exchanger bracket 22 are generally adapted to the fan (not shown) inside the air conditioner 100. For example, the fan is a vertical cross-flow fan, the indoor heat exchanger 21 has a three- or four-piece structure and is arranged around the cross-flow fan, and the heat exchanger bracket 22 is a frame shape surrounding the indoor heat exchanger 21. The fan drives air to be blown in from the air inlet (not shown) of the casing 1, then flows through the indoor heat exchanger 21, and then blown out from the air outlet 12.

[0063] Specifically, the air conditioner 100 has a support frame 9, which is installed inside the casing 1. The heat exchanger bracket 22 is installed and fixed on the support frame 9, and the indoor heat exchanger 21 is fixed on the heat exchanger bracket 22.

[0064] In some specific embodiments, such as Figure 9 As shown, the support frame 9 includes two vertical rods. The bottom of the support frame 9 is connected to the base 14. The heat exchanger bracket 22 is located above the base 14 and connected to the two vertical rods. The housing 1 is connected above the base 14 and is fitted around the support frame 9 and the heat exchanger bracket 22.

[0065] Furthermore, such as Figure 9 As shown, the humidifier 3 is connected to the support frame 9, the water tank 4 is installed on the support frame 9 below the heat exchanger bracket 22, and the steam generator 5 is installed on the support frame 9 above the heat exchanger bracket 22. In this way, the humidifier 3 and the heat exchanger 2 are integrated into one unit through the support frame 9, improving the overall structural reliability.

[0066] Optionally, the stand 9 is connected to the housing 1 and the base 14 by fasteners 91, and the humidifying device 3 is connected to the stand 9 by fasteners 91, etc.

[0067] In some designs, the air conditioner 100 has a cooling mode, where the water vapor generated by the steam generator 5 mixes with the cold air to increase indoor humidity. In other designs, the air conditioner 100 has a heating mode, where the water vapor generated by the steam generator 5 mixes with the hot air to increase indoor humidity. In still other designs, the air conditioner 100 has a fan mode, in which the indoor heat exchanger 21 does not perform cooling or heating, and the water vapor generated by the steam generator 5 mixes with the room temperature air to increase indoor humidity.

[0068] Here, the location of the steam generated by the steam generator 5 is not limited; it can be directly directed to the air outlet 12, or it can be located upstream of the indoor heat exchanger 21 in the airflow path. The location of the steam generated by the steam generator 5 can also be between the indoor heat exchanger 21 and the air outlet 12; there is no limitation here.

[0069] In some embodiments, such as Figures 4-5 As shown, the steam generator 5 includes a support box 52 and a heating element 59. The support box 52 defines a receiving cavity 54. The support box 52 is provided with partition ribs 53 to divide the receiving cavity 54 into a water inlet cavity 541, a heating cavity 542, and an exhaust cavity 543. The water inlet cavity 541 and the heating cavity 542 are connected through a first connecting port 55, and the heating cavity 542 and the exhaust cavity 543 are connected through a second connecting port 56. The water inlet cavity 541 is connected to the water inlet 525 of the steam generator 5, and the exhaust cavity 543 is connected to the steam outlet 51 of the steam generator 5.

[0070] The supporting box 52 is divided into a water inlet chamber 541, a heating chamber 542 and an exhaust chamber 543 by the partition rib 53. The water introduced by the water pump 7 flows through the water inlet chamber 541, the heating chamber 542 and the exhaust chamber 543 in sequence. The heating element 59 is used to heat the water in the heating chamber 542. The water vapor generated by heating is discharged through the steam port 51 connected to the exhaust chamber 543.

[0071] The partition rib 53 and the first connecting port 55 and the second connecting port 56 allow water to flow between the water inlet chamber 541, the heating chamber 542 and the exhaust chamber 543, while also limiting the water flow speed and flow impact force, so that each chamber can better perform its function after becoming independent.

[0072] The heating chamber 542 is independently configured, allowing the heating element 59 to concentrate the heating of the water within it. Since the water volume in the heating chamber 542 is relatively small, it can quickly absorb heat and heat up, converting into water vapor in a short time. This accelerates the generation of water vapor and reduces humidification waiting time. Thus, when the air conditioner 100 enters humidification mode, the humidification device 3 can respond quickly, providing rapid humidification.

[0073] The water inlet chamber 541 is independently designed to buffer water volume. Water from the water tank 4, driven by the water pump 7, first enters the water inlet chamber 541 via the water pipe 6. The partition rib 53 between the water inlet chamber 541 and the heating chamber 542 prevents water pumped in through the water inlet 525 from rushing into the heating chamber 542, thus avoiding a sudden drop in water temperature caused by a large amount of low-temperature water directly entering the heating chamber 542. In this way, the water in the heating chamber 542 can maintain a continuous heating and evaporation state, and the resulting water vapor is less likely to condense upon cooling, ensuring stable humidification.

[0074] The heating chamber 542 and the water inlet chamber 541 are connected by the first connecting port 55, so that the water inlet chamber 541 slowly and steadily replenishes water to the heating chamber 542.

[0075] By independently configuring the exhaust chamber 543, the steam outlet 51 is separated from the heating chamber 542, reducing the likelihood of boiling water rushing towards the steam outlet 51. Furthermore, the heated water tends to settle in the exhaust chamber 543, and the water droplets and mist within it flow downwards after settling, making them less likely to mix with the steam during discharge. This facilitates the separation of water vapor from water droplets, increasing the content of discharged water vapor. Moreover, the amount of water droplets and mist formed by the steam generator 5 within and after exiting the air conditioner 100 is reduced.

[0076] Optionally, the steam outlet 51 is located at the top of the exhaust chamber 543, so that the steam generated by heating floats upward. The steam outlet 51 located at the top of the exhaust chamber 543 helps to increase the water capacity within the steam generator 5 and reduces the likelihood of water spraying outwards. Of course, in some embodiments of this application, it is not excluded that the steam outlet 51 may be located on the side wall of the exhaust chamber 543.

[0077] Specifically, the first connecting port 55 and the second connecting port 56 are respectively located near the bottom of the receiving cavity 54, which can make the water levels in the water inlet cavity 541, the heating cavity 542 and the exhaust cavity 543 roughly the same, which is conducive to maintaining water flow, replenishing water to the heating cavity 542 in a timely manner, and reducing the probability of the heating cavity 542 burning dry.

[0078] Optionally, the first connecting opening 55 is located on the partition rib 53 between the water inlet chamber 541 and the heating chamber 542, which can reduce the processing difficulty. This application does not exclude the possibility that in some embodiments, the first connecting opening 55 is formed on the inner wall of the support box 52, rather than on the partition rib 53.

[0079] Optionally, the second connecting opening 56 is located on the partition rib 53 between the heating chamber 542 and the exhaust chamber 543, which can reduce the difficulty of processing. This application does not exclude the possibility that in some embodiments, the second connecting opening 56 is formed on the inner wall of the support box 52, rather than on the partition rib 53.

[0080] In the solution of this application, the water inlet chamber 541 and the heating chamber 542 are not limited to being connected through the first connecting port 55. For example, the partition rib 53 between the water inlet chamber 541 and the heating chamber 542 is lower, and air is kept above the water inlet chamber 541 and the heating chamber 542 to maintain air pressure balance.

[0081] In the solution of this application, the heating chamber 542 and the exhaust chamber 543 are not limited to being connected through the second communication port 56. For example, the partition rib 53 between the heating chamber 542 and the exhaust chamber 543 is lower, and air can also be maintained above the heating chamber 542 and the exhaust chamber 543 to maintain air pressure balance.

[0082] In this application, the water inlet 525 and the steam outlet 51 can be provided as one or more. Providing multiple steam outlets 51 allows water vapor to be discharged quickly and efficiently from the steam outlet 51. Providing multiple water inlets 525 makes the water replenishment process faster and reduces the impact force of water rushing in when water enters through a single outlet.

[0083] In this application, the type of heating element 59 is not limited; it can be a heating plate, a heating rod, or a heating wire. Using an electric heating wire as the heating element 59 provides a large coverage area and a larger heat exchange area. Using a heating rod or heating plate as the heating element 59 facilitates assembly and replacement. Of course, the heating element 59 in this application is not limited to these; it can also be a refrigerant heating element, etc., connected to a compressor, allowing high-temperature refrigerant to flow through the heating element 59, thereby increasing the water temperature and converting it into water vapor.

[0084] In some embodiments, such as Figures 5-7 As shown, the humidification device 3 includes a liquid level detector 8, which is connected to the steam generator 5 and electrically connected to the water pump 7. The water pump 7 adjusts its operating status according to the detection result of the liquid level detector 8.

[0085] The water level in the housing 54 of the steam generator 5 is detected by a level detector 8. A water pump 7, electrically connected to the level detector 8, receives the detection signal. When the detection signal indicates that the water level in the housing 54 of the steam generator 5 is low, meaning it is in a water shortage state, the water pump 7 replenishes water to the steam generator 5. When the detection signal indicates that the water level in the housing 54 of the steam generator 5 is high, meaning it is in a sufficient water state, the water pump 7 shuts off, stopping the water replenishment operation.

[0086] Automatic control of the water level in the steam generator 5 is achieved through signal transmission between the level detector 8 and the water pump 7, preventing the heating element 59 from burning out due to insufficient water in the steam generator 5, while maintaining the water level in the steam generator 5 within a suitable range.

[0087] It is understandable that the liquid level detector 8 and the water pump 7 are electrically connected to achieve signal transmission between them. Therefore, the liquid level detector 8 and the water pump 7 can be connected by a wired data cable or by a wireless communication connection to achieve signal transmission. In the following text, "electrical connection" will be used to refer to both wired data cable connection and wireless communication connection.

[0088] Of course, the proposed solution is not limited to this; some solutions may not include a liquid level detector 8. In some solutions, the operating status of the water pump 7 can be controlled by a pre-set heating time program. For example, every time the heating element 59 heats for the first time t1, the water pump 7 drives water replenishment, adding a quantity of m1 water to the receiving cavity 54.

[0089] In comparison, controlling the water replenishment process through the liquid detector 8 provides higher control precision and better reliability in preventing dry burning.

[0090] In some specific embodiments, such as Figure 7 As shown, the liquid level detector 8 includes a detection box 81, a float component 82, and a sensor 83. The detection box 81 is connected to the support box 52 and has a float cavity 84 communicating with the receiving cavity 54. The float component 82 is disposed within the float cavity 84. The sensor 83 is disposed on the detection box 81 and is used to sense the rise and fall of the float component 82. The sensor 83 is electrically connected to the water pump 7.

[0091] The float chamber 84 is connected to the receiving chamber 54, allowing the float chamber 84 to have the same water level as the receiving chamber 54, meaning the water level in the float chamber 84 rises and falls synchronously with the water level in the receiving chamber 54. The sensor 83 works in conjunction with the float element 82 within the float chamber 84, and detects the water level in the receiving chamber 54 by sensing the rise and fall of the float element 82, obtaining a water level detection signal, which is then sent to the water pump 7 to adjust its operating state, thus achieving automatic water level control in the receiving chamber 54 of the steam generator 5. This level detector 8 not only has high detection accuracy but also a simple structure, is not easily damaged by water flow impact, and has a long service life.

[0092] Optionally, the sensing element 83 is a Hall switch, which, together with the float element 82, constitutes a float-type level gauge based on the Hall effect. The float element 82 uses a magnetic float to indicate the liquid level, and a Hall element matrix serves as the sensing element 83. The float contains a magnet, and the Hall element matrix consists of a series of Hall switch elements, each 1.5 mm wide, arranged closely from top to bottom. The magnetic force of the magnet acts on the measurement matrix composed of the Hall switch elements, which converts the water level height into a high-level pulse signal. This signal is then transmitted to the signal acquisition and processing unit and sends start / stop commands to the water pump 7.

[0093] Furthermore, the sensing element 83 also includes a microcontroller and a counter, with a scanning program set in the microcontroller for signal acquisition and processing.

[0094] The measurement process is as follows: First, a reference position C is set. The program in the microcontroller is executed to start scanning the Hall element matrix, and a counter is started simultaneously. The magnetic float will cause the Hall element at the water level to generate a high-level signal. During the scanning of the Hall element matrix, the counter stops counting when a high-level signal is encountered. The counter value is judged and converted to obtain the relative height H of the water level with respect to the reference position C. Adding this to the actual height of the reference position C gives the actual water level. After obtaining the actual water level, the sensor 83 sends start / stop commands to the water pump 7 based on the actual water level.

[0095] The sensor 83 can transmit signals to the water pump 7 via a communication interface. Optionally, the communication interface can be an RS-485 interface, which can realize wireless connection between the liquid level detector 8 and the water pump 7, reducing wiring.

[0096] In some specific embodiments, such as Figures 4-6 As shown, the float cavity 84 is connected to the receiving cavity 54 through a third connecting port 57 and a fourth connecting port 58. The third connecting port 57 is configured to be at least partially higher than the highest liquid level in the receiving cavity 54, and the fourth connecting port 58 is configured to be at least partially lower than the lowest liquid level in the receiving cavity 54.

[0097] The minimum and maximum liquid levels represent the following: when the water level in the receiving cavity 54 is lower than the minimum level, the water pump 7 needs to replenish the receiving cavity 54; when the water level in the receiving cavity 54 reaches the maximum level, the water pump 7 does not need to continue replenishing the receiving cavity 54. By setting the minimum and maximum liquid levels, the water level in the receiving cavity 54 is kept within a preset range.

[0098] The fourth connecting port 58 is designed to ensure that the water levels in the receiving cavity 54 and the float cavity 84 are the same. Water in the receiving cavity 54 flows into the float cavity 84 through the fourth connecting port 58, and the water level in the float cavity 84 can reach below the minimum liquid level of the receiving cavity 54. When the sensor 83 senses that the water level in the float cavity 84 has dropped to the minimum liquid level, that is, when the float 82 has dropped to the minimum liquid level, the sensor 83 sends a signal to the water pump 7 to control the water pump 7 to replenish water into the receiving cavity 54. To make the synchronization of water levels between the receiving cavity 54 and the float cavity 84 smoother, the fourth connecting port 58 is located below the receiving cavity 54 and the float cavity 84 and connects to the bottom of the cavity to ensure that the water level in the receiving cavity 54 is always synchronized with the float cavity 84.

[0099] The third connecting port 57 is provided to enable air communication between the receiving cavity 54 and the float cavity 84, so that the float cavity 84 can be ventilated through the third connecting port 57 during the process of synchronizing the liquid level of the receiving cavity 54, and to prevent negative pressure from being generated in the float cavity 84, which would prevent water in the receiving cavity 54 from flowing into the float cavity 84.

[0100] When the sensor 83 senses that the float 82 in the float cavity 84 has risen to the highest liquid level in the receiving cavity 54, the sensor 83 sends a signal to the water pump 7 to control the water pump 7 to stop replenishing water into the receiving cavity 54. At this time, the water level in the receiving cavity 54 is at the highest liquid level, and the third connecting port 57 is at least partially above the highest liquid level. The receiving cavity 54 and the float cavity 84 can always maintain an air connection, ensuring that the water levels in the receiving cavity 54 and the float cavity 84 are synchronized.

[0101] The minimum and maximum liquid levels can be preset in the microcontroller program of the sensor 83. The sensor 83 determines the state of the water level in the containment cavity 54 by comparing the measured actual water level height, the minimum liquid level, and the maximum liquid level, and then sends a start / stop command to the water pump 7 to control whether the water pump 7 replenishes water, thereby automatically controlling the water level in the containment cavity 54.

[0102] Specifically, such as Figure 5 As shown, the support box 52 is provided with two first pipes 526 on one side adjacent to the exhaust chamber 543, and the detection box 81 is provided with two second pipes 527. The first pipes 526 and the second pipes 527 are connected by insertion, and the two first pipes 526 respectively form a third connecting port 57 and a fourth connecting port 58.

[0103] The third connecting port 57 and the fourth connecting port 58 are located on the exhaust chamber 543 of the receiving chamber 54. Water heated from the heating chamber 542 flows into the float chamber 84 after passing through the receiving chamber 54 to achieve water level synchronization.

[0104] Since the water in the heating chamber 542 is boiling after being heated, the boiling hot water will churn and generate violent fluctuations. If the water surface fluctuates violently, the float 82 will also fluctuate up and down, causing the float 82 to fail to accurately reflect the water level, thus affecting the water level detection results.

[0105] By separating the exhaust chamber 543, heating chamber 542, and float chamber 84, the fluctuation of boiling hot water flowing from heating chamber 542 into exhaust chamber 543 can be buffered within exhaust chamber 543, further reducing the fluctuation of water flowing into float chamber 84. This reduces the additional up-and-down fluctuations of float component 82 caused by the fluctuation of boiling hot water in heating chamber 542, thereby improving the accuracy of the water level reflected by float component 82 and improving the detection accuracy of level detector 8.

[0106] Meanwhile, the exhaust chamber 543 can also buffer the temperature of boiling hot water, reduce the heat conduction of boiling hot water to the float component 82, and ensure the detection accuracy of the float component 82.

[0107] In this application, the support box 52 and the detection box 81 are connected by a first connecting pipe 526 and a second connecting pipe 527, which realizes a detachable connection, is easy to install, and is also convenient for subsequent maintenance and replacement.

[0108] Of course, the arrangement of the third connecting port 57 and the fourth connecting port 58 is not limited to this. In some schemes, the third connecting port 57 and the fourth connecting port 58 can be connected vertically to form a strip connecting port. The strip connecting port is constructed such that it is at least partially higher than the highest liquid level and at least partially lower than the lowest liquid level. The two first connecting pipes 526 are vertically connected to each other to form a first strip connecting pipe, and the two second connecting pipes 527 are vertically connected to each other to form a second strip connecting pipe. The support box 52 and the detection box 81 are connected by the first strip connecting pipe and the second strip connecting pipe. During the connection process, only one alignment is required, making the installation more convenient.

[0109] Furthermore, such as Figure 5 As shown, the receiving cavity 54 also includes a buffer cavity 544, which is located between the heating cavity 542 and the exhaust cavity 543. The upper end of the partition rib 53 is lower than the height of the receiving cavity 54 so that the tops of the water inlet cavity 541, the heating cavity 542 and the exhaust cavity 543 are connected.

[0110] Water in heating chamber 542 flows into exhaust chamber 543 through buffer chamber 544. The buffer chamber 544 provides a first buffer for the boiling hot water flowing into heating chamber 542. The boiling hot water in buffer chamber 544 then flows into exhaust chamber 543 for a second buffer, gradually reducing the fluctuation effect of boiling hot water. Finally, the water flowing into float chamber 84 is level and stable, further reducing the impact of water flow fluctuation caused by boiling on float component 82, and simultaneously improving the detection accuracy of level detector 8.

[0111] The upper end of the partition rib 53 is lower than the height of the receiving cavity 54. During the water filling process, the water inlet cavity 541, heating cavity 542 and exhaust cavity 543 can be ventilated through the part connected at the top, so as to avoid the negative pressure that prevents water flow from being generated in the cavity due to the cavity sealing, so as to ensure that the water can flow smoothly through the water inlet cavity 541, heating cavity 542 and exhaust cavity 543.

[0112] Furthermore, such as Figure 4 and Figure 5As shown, the steam generator 5 also includes an insulation box 3a that is fitted over the support box 52. The insulation box 3a reduces heat loss from the support box 52, improving the efficiency of steam generation while saving electricity. To enhance insulation, the insulation box 3a is a shell structure that covers the support box 52. After the support box 52 is placed inside the insulation box 3a, the four walls of the support box 52 fit snugly against the insulation box 3a, reducing the space occupied by the insulation box 3a and making the structure of the steam generator 5 more compact.

[0113] Optionally, an insulation layer may be provided on the insulation box 3a, which may be any one or a combination of polystyrene foam layer, polyurethane foam layer, extruded polystyrene board, phenolic foam layer, phenolic resin layer, and glass wool layer.

[0114] In some specific embodiments, such as Figure 4 and Figure 5 As shown, the steam generator 5 also includes a protective box 3b that is fitted over the support box 52, and even the support box 52 is covered by an insulation box 3a, which is covered by a protective box 3b.

[0115] The protective box 3b provides structural support and protection for the insulation box 3a and the support box 52, reducing the risk of damage from collisions between the support box 52 or the insulation box 3a and other components. To enhance protection, the protective box 3b includes a protective casing and a protective cover. The protective casing and cover interlock to enclose the insulation box 3a, which contains the support box 52, within the protective box 3b. The protective casing and cover are connected and secured using bolts or clips.

[0116] The protective case 3b is constructed of a rigid material, either metal or rigid plastic, to ensure sufficient strength to resist impacts. Optionally, reinforcing ribs can be added to the protective case 3b to further enhance its strength.

[0117] Specifically, when the support box 52 is provided with a first connecting pipe 526, in order to facilitate the connection between the first connecting pipe 526 and the second connecting pipe 527, such as Figure 4 As shown, clearance notches are provided on the insulation box 3a and the protective box 3b respectively. The clearance notches are provided corresponding to the first connecting pipe 526 to facilitate the insertion of the first connecting pipe 526 and the second connecting pipe 527.

[0118] In some specific embodiments, such as Figures 4-5As shown, the support box 52 includes a steam tank body 521, a steam tank upper cover 522, and a steam tank lower cover 523. The top of the steam tank body 521 is open, and a mating opening 524 is provided at the bottom of the steam tank body 521. A partition rib 53 is integrally connected inside the steam tank body 521. The steam tank upper cover 522 is connected to the top of the steam tank body 521. The steam tank lower cover 523 is connected to the mating opening 524 at the bottom of the steam tank body 521, and the heating element 59 is installed on the steam tank lower cover 523.

[0119] The steam tank 521 of the support box 52 has an internal cavity 54, which is divided into a water inlet cavity 541, a heating cavity 542, and an exhaust cavity 543 by built-in partition ribs 53. The steam tank cover 522 is installed on the steam tank 521 from above to cover the upper opening of the steam tank 521 and reduce the amount of dust and debris falling into the steam tank 521. The steam tank lower cover 523 is installed on the steam tank 521 from the lower mating port 524 and is used to fix the heating element 59 at the mating port 524 to protect and fix the heating element 59.

[0120] Optionally, the lower cover 523 and the upper cover 522 of the steam tank are interlocked to form a box that encloses the steam tank body 521 inside, so as to further enhance the protection of the steam tank body 521.

[0121] Of course, such as Figure 4 As shown, in order to enhance the airtightness of the upper opening of the steam tank cover 522 and the upper opening of the steam tank body 521, a sealing ring is provided around the upper opening of the steam tank body 521. When the upper cover 522 is fastened to the upper opening of the steam tank body 521, it is pressed against the sealing ring to reduce the leakage of water vapor from the fastening point of the steam tank body 521 and the upper cover 522.

[0122] Furthermore, such as Figures 4-5 As shown, the humidification device 3 includes a steam pipe 3c. One end of the steam pipe 3c is connected to the steam port 51 of the steam generator 5, and the other end of the steam pipe 3c extends downward to the air outlet 12 or into the air outlet duct of the air conditioner 100.

[0123] The water vapor generated in the steam generator 5 enters the steam pipe 3c through the steam port 51, and is then transported along the steam pipe 3c to the air outlet 12 or the air duct of the air conditioner. This allows the water vapor to enter the surrounding environment along with the airflow from the air conditioner, thereby humidifying the surrounding environment. The steam pipe 3c is designed to guide the water vapor to a set location, thus preventing water vapor from flowing inside the casing 1 and causing excessive water accumulation or mold growth inside the casing 1.

[0124] Optionally, to further improve the utilization rate of the generated water vapor, such as Figure 3As shown, the extended end of the steam pipe 3c extends to the top of the air outlet 12, and the air outlet end of the steam pipe 3c is set towards the air outlet 12. Water vapor is discharged from the top of the air outlet 12 towards the air outlet 12, so that the water vapor can be fully mixed into the flowing air of the air outlet 12, increasing the water vapor content in the flowing air, thereby improving the utilization rate of water vapor and the humidification effect of the air conditioner.

[0125] Furthermore, such as Figure 2 , Figure 8 As shown, the humidifying device 3 also includes a mounting frame 3d, which has a conversion chamber 3e. A water tank 4 is mounted on the mounting frame 3d, and the outlet 41 of the water tank 4 connects to the conversion chamber 3e. A water pump 7 is connected to one side of the mounting frame 3d and is connected to the conversion chamber 3e. The mounting frame 3d facilitates the installation of the water tank 4 and provides support and protection. The conversion chamber 3e on the mounting frame 3d allows water to flow, reducing the difficulty of pipe connection.

[0126] The conversion chamber 3e serves as a water storage structure and can be constructed as a tank or a box. The water pump 7 is connected to the bottom of the conversion chamber 3e to ensure that as much water as possible in the conversion chamber 3e is pumped to the steam generator 5.

[0127] Furthermore, the water pump 7 and the conversion chamber 3e, as well as the water tank 4 and the conversion chamber 3e, are connected by connecting pipes so that the water pump 7 and the water tank 4 do not need to be installed together, making it easier to select the installation position of the water pump 7 and the water tank 4, and helping to optimize the spatial layout of the installation chamber 11.

[0128] Furthermore, such as Figure 3 , Figure 9 As shown, the air conditioner 100 includes a vertically arranged frame 9, a water tank 4 fixed to the bottom of the frame 9, a steam generator 5 fixed to the top of the frame 9, and a heat exchange device 2 connected to the frame 9. The frame 9 is connected to the casing 1 by fasteners 91. This integrates the main internal structure of the air conditioner 100 into one unit, improving overall stability and reducing vibration and noise during airflow.

[0129] Optionally, the mounting bracket 3d is fixed to the upright frame 9 by mounting sheet metal 3f. Further, the mounting bracket 3d and the mounting sheet metal 3f, and the mounting sheet metal 3f and the upright frame 9 are fixed by bolts.
