Description

Technical Field

[0001] This application relates to the field of air handling technology, and more particularly to an air conditioner. Background Technology

[0002] To meet consumer demand, more and more cabinet air conditioners are incorporating humidification systems. However, the addition of humidification systems has a significant impact on the internal layout of cabinet air conditioners. In order to make room for the humidification system, the air duct and the electrical box of the fresh air module need to be redesigned.

[0003] Cabinet air conditioners with integrated humidification systems have development potential. For cabinet air conditioners with humidification and fresh air modules, innovation in structural design and overall layout is required to ensure the balance between the modules and meet diverse needs. Designers need to balance performance, cost and user experience to create a truly humanized air solution that meets the humidification function requirements of cabinet air conditioner products, achieves modular humidification, and facilitates user operation.

[0004] In existing cabinet air conditioners with integrated humidification systems, some have a top-integrated humidification module, located at the top of the unit and directly connected to the air duct. The advantages of this design are lower air resistance and the direct connection to the duct allows the humidified air to be carried out by the air conditioning, improving humidification efficiency. However, maintenance requires disassembling the top cover, making operation complex, and the direct-connection humidification solution has a high failure rate, resulting in inconvenience and a poor user experience. Other designs use a bottom-mounted independent humidification compartment with a modular, independent design that supports heat exchange and recovery. The advantages are a pull-out design, independent modules, and convenient maintenance. The disadvantages are that it occupies a significant amount of bottom space, and the wet-film humidification method poses a risk of bacterial growth. Still other designs combine a wet-film humidification module with a fresh air intake design. The wet film is placed between the fresh air outlet and the filter module, with the fresh air carrying the humidified air to the outside of the machine. The advantages of this design are convenient wet film replacement and efficient use of humidification space. The disadvantages are that the wet film is expensive, requiring frequent replacement, and the risk of bacteria growth on the wet film being blown into the room by the fresh air, potentially harming human health. Summary of the Invention

[0005] This application provides an air conditioner with an integrated humidification module design, eliminating the need for a separate water tank. The overall layout is reasonable, with high space utilization, and does not affect the performance and use of other functions. By setting a float switch, a liquid level difference is formed between the humidification outer cover and the humidification chamber. The water level in the humidification chamber is slightly higher than the surface of the heating element, which improves the humidification efficiency and shortens the humidification preparation time.

[0006] An air conditioner includes a cabinet unit, which includes a housing and a humidification module. The housing has an inner cavity defined inside. The humidification module is disposed within the inner cavity. The humidification module includes: a humidification cover, a humidification chamber, a heating element, and a float switch. The humidifying outer cover is used to store water; the humidifying chamber is fitted inside the humidifying outer cover, has a water inlet, and is connected to the humidifying outer cover through the water inlet; the heating element is located inside the humidifying chamber and is used to heat water to form humidifying air; a float switch is installed at the water inlet to control water to enter the humidifying chamber from the humidifying outer cover. The float switch includes a switch cavity and a float. The switch cavity is internally defined to form a channel, with a float switch inlet and a float switch outlet located at both ends of the channel and communicating with the channel. The opening direction of the float switch outlet is towards the direction in which the water level in the humidification cavity decreases. The float is disposed in the humidification cavity, rising as the water level in the humidification cavity rises and falling as the water level in the humidification cavity falls. When the water level in the humidification cavity is higher than that of the heating element, the float switch outlet is blocked, and when the water level in the humidification cavity is lower than that of the heating element, the float switch outlet is moved away from the float switch outlet to connect the humidification outer cover and the humidification cavity.

[0007] The above technical solution has the following advantages or beneficial effects: The humidification module of the air conditioner adopts a humidification outer cover and humidification cavity structure. The liquid is located between the humidification cavity and the humidification outer cover, and the water connection between the humidification cavity and the liquid is controlled by a float switch. The float rises as the water level in the humidification cavity rises and falls as the water level in the humidification cavity falls. When the water level in the humidification cavity is higher than the heating element, or slightly higher than the surface of the heating element, the float blocks the outlet of the float switch, and the water in the humidification outer cover no longer flows into the humidification cavity. As the heating element heats the surrounding water to form humidified air, the water level in the humidification cavity drops, and the float also falls and moves away from the outlet of the float switch, connecting the humidification outer cover and the humidification cavity. The water in the humidification outer cover flows into the humidification cavity, carrying the float up. The distance between the float and the outlet becomes smaller and smaller. When the water level in the humidification cavity reaches a critical value, the water level stabilizes, and the float blocks the outlet of the float switch again.

[0008] The aforementioned humidification module adopts an integrated design, eliminating the need for a separate water tank. This results in a rational overall layout and high space utilization, without affecting the performance and use of other functions. Furthermore, by incorporating a float switch, a liquid level difference is created between the humidification outer casing and the humidification chamber, with the water level in the humidification chamber slightly higher than the heating element surface. This improves humidification efficiency and shortens preparation time. Simultaneously, the float switch design avoids the use of commonly used one-way valves, resulting in higher integration of the humidification module. The float switch directly controls its outlet; when the water level reaches the set point, the outlet is blocked, making operation more convenient.

[0009] In addition, the aforementioned integrated humidification module structure adopts a water filling design where the humidification module is completely removed, and the water is stored inside the humidification outer cover, separated from the humidification chamber. To improve humidification efficiency, a float-type water level switch design is used, which controls the water level in the humidification chamber. The heating area of ​​the heating element is small, and this design can effectively isolate heat transfer, preventing users from getting burned when removing the humidification module.

[0010] In some embodiments, the float switch further includes a guide for limiting the range of float movement in the direction of rising and falling water levels.

[0011] The above technical solution has the following advantages or beneficial effects: the guide component guides the upward and downward trajectory of the float, preventing the float from changing position within the humidification chamber due to water fluctuations, thus avoiding blockage of the float switch outlet. Regarding the structural form of the guide component, it can be a guide structure with an elongated groove. The float has a protrusion adapted to the elongated groove, and the groove extends along the direction of water level rise and fall within the humidification chamber. The protrusion cooperates with the elongated groove to guide the float.

[0012] In some embodiments, the float is provided with rubber adapted to block the outlet of the float switch.

[0013] The above technical solution has the following advantages or beneficial effects: by setting rubber that is compatible with the outlet of the float switch, it is beneficial to improve the sealing effect of the float switch outlet when the float switch is in use, thereby forming a liquid level difference between the humidification outer cover and the humidification chamber, so that the water level in the humidification chamber is slightly higher than the surface of the heating element, which improves the humidification efficiency and shortens the humidification preparation time.

[0014] In some embodiments, the humidification chamber is disposed on the side near the humidification cover.

[0015] The above technical solution has the following advantages or beneficial effects: the heating element is set inside the humidification chamber, and the humidification chamber is set on one side of the humidification cover. When water needs to be added, the side where the humidification chamber is located can be avoided when the humidification module is completely removed, preventing the user from getting burned when removing the humidification module. Furthermore, this setting is also conducive to isolating heat transfer, so that the heating element can heat the surrounding water more efficiently to generate humidified air, thereby improving the humidification efficiency.

[0016] In some embodiments, the humidification chamber includes a water inlet chamber and a heating chamber connected to the water inlet chamber. The water inlet chamber has a water inlet, and the heating chamber is provided with a heating element. The heating chamber is located on the side near the humidification cover.

[0017] The above technical solution has the following advantages or beneficial effects: Dividing the humidification chamber into a water inlet chamber and a heating chamber connected to the water inlet chamber, and separating the water inlet of the humidification chamber from the heating element, prevents heat radiated by the heating element from overflowing through the water inlet of the humidification chamber. This not only helps to isolate heat transfer but also avoids potential burns. Simultaneously, placing the heating chamber on one side of the humidification cover, with the heating element located within the heating chamber, concentrates the heating area within the heating chamber. On the one hand, when adding water, the side where the heating chamber is located can be avoided when completely removing the humidification module, preventing burns to the user's hands during disassembly. Furthermore, this arrangement also helps to isolate heat transfer, allowing the heating element to more efficiently heat the surrounding water to generate humidified air, thereby improving humidification efficiency.

[0018] In some embodiments, a humidification chamber cover for sealing the water inlet chamber is provided on the side of the water inlet chamber away from the heating chamber.

[0019] The above technical solution has the following advantages or beneficial effects: by setting a humidification chamber cover, the float switch can be maintained after the humidification chamber cover is opened, which facilitates maintenance. At the same time, the humidification chamber cover is set away from the heating chamber, which is also conducive to isolating heat transfer.

[0020] In some embodiments, the bottom surface of the heating cavity is provided with a heating element base for mounting the heating element, and the heating element base encloses the heating cavity.

[0021] The above technical solution has the following advantages or beneficial effects: the heating element can be directly maintained after the heating element base is opened, which facilitates the maintenance of the heating element. At the same time, the scale in the electric heating area inside the humidification chamber is relatively concentrated, and it can be directly cleaned after the heating element base is disassembled.

[0022] The above-mentioned integrated steam humidification module is easy to install and disassemble. Since there is no water tank, it is easy to clean between the humidification chamber and the humidification cover. The installation is done by rubber compression, which is convenient and quick. The scale is concentrated in the electric heating area inside the humidification chamber. It can be cleaned directly after disassembly. The maintenance of the float position can be completed by removing the humidification chamber cover.

[0023] In some embodiments, the top surface of the heating cavity is provided with an air outlet, and the housing is provided with an air outlet. The air outlet and the air outlet are connected by a humidification pipe.

[0024] The above technical solution has the following advantages or beneficial effects: the heating element heats the water in the heating chamber, and the generated humidified air is transported through the air outlet and the humidification pipe, and discharged into the room through the air outlet to achieve the regulation of indoor humidity.

[0025] In some embodiments, the inner cavity includes a first cavity, a second cavity, and a third cavity arranged sequentially from top to bottom along the height direction of the cabinet unit. The first cavity is connected to the room through an air outlet. The first cavity and the second cavity are separated by a first partition. The first cavity is provided with a second partition that divides the first cavity into a mixing cavity and a fresh air cavity. The humidification pipe passes through the first partition and is connected to the mixing cavity. The humidified air and part of the fresh air are mixed in the mixing cavity and then enter the room through the air outlet. Another part of the fresh air enters the room through the fresh air cavity and then through the air outlet. The second partition is a bent plate that bends toward the mixing cavity.

[0026] The above technical solution has the following advantages or beneficial effects: By setting a second baffle, the humidified air is mixed with a portion of the fresh air in the mixing chamber before being discharged, avoiding the humidified air from mixing with the fresh air throughout the first chamber, which would cause a large amount of humidifying vapor to condense. The humidified air is discharged after mixing with a portion of the fresh air in the mixing chamber, and the humidification outlet occupies a portion of the fresh air space, leaving sufficient space for mixing with the fresh air while minimizing the impact on the fresh air volume, thus ensuring that the humidification outlet is cooled to a temperature that is not too hot to the touch. Simultaneously, the second baffle is a bent plate that bends towards the mixing chamber, preventing the liquid water condensed on the second baffle from being carried out of the outlet with the fresh air, thus ensuring a pleasant user experience.

[0027] In some embodiments, the cabinet unit further includes a total heat exchange module, a fresh air module, and an electrical control box; the fresh air module and the electrical control box are located in the third cavity, and the total heat exchange module and the humidification module are located in the second cavity.

[0028] The above technical solution has the following advantages or beneficial effects: The cabinet air conditioner mainly consists of the following modules. Divided by a belt, the upper part of the air conditioner (above the belt) mainly consists of the air conditioning duct and heat exchange module. The lower part (below the belt) mainly consists of the humidification module, the total heat exchange module, the fresh air module, and the electrical control box. Because the fresh air module is compatible with the integrated intake and exhaust design and involves the total heat exchange module, to ensure the airflow of the fresh air module and to achieve a steam humidification layout that does not occupy space from other air conditioning modules, an integrated humidification module is designed in the gap of the fresh air volute. The humidification module and the total heat exchange module are at the same vertical height, not occupying space in the electrical control box. The space between the humidification and total heat exchange modules is reserved for wiring in the electrical control box, improving the overall integration of the cabinet air conditioner with the humidification module.

[0029] The design of the humidification module in this cabinet air conditioner utilizes the space next to the air conditioner casing. Without affecting the casing size or air conditioning piping, it makes reasonable use of a portion of the space in the panel base and rear cover to achieve convenient installation and easy maintenance of the humidification module.

[0030] An air conditioner includes a cabinet unit, which includes a casing and a humidification module. An inner cavity is defined within the casing. The humidification module is located within the inner cavity. The humidification module includes a humidification outer cover, a humidification chamber, a heating element, and a float switch. The humidification outer cover stores water. The humidification chamber is fitted inside the humidification outer cover and has a water inlet, which is connected to the humidification outer cover. The heating element is located within the humidification chamber and heats the water to create humidified air. The float switch is installed at the water inlet and disconnects the connection between the humidification outer cover and the humidification chamber when the water level in the humidification chamber is higher than the heating element, and connects the humidification outer cover and the humidification chamber when the water level in the humidification chamber is lower than the heating element.

[0031] The above technical solution has the following advantages or beneficial effects: The humidification module adopts an integrated design, eliminating the need for a separate water tank, resulting in a reasonable overall layout and high space utilization. It does not affect the performance and use of other functions. Furthermore, by using a float switch, a liquid level difference is created between the humidification outer cover and the humidification chamber, with the water level in the humidification chamber slightly higher than the surface of the heating element, improving humidification efficiency and shortening preparation time. Simultaneously, the float switch avoids the use of commonly used one-way valves, resulting in higher integration of the humidification module. The float switch directly controls the float switch outlet; when the water level reaches the required level, the outlet is blocked, making operation more convenient. In addition, the integrated humidification module structure uses a design where water is added only after the humidification module is completely removed. Water is stored inside the humidification outer cover, separated from the humidification chamber. To improve humidification efficiency, a float-type water level switch design is used, controlling the water level in the humidification chamber. The heating area of ​​the heating element is small, and this design effectively isolates heat transfer, preventing burns when the user removes the humidification module. Attached Figure Description

[0033] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0038] The compressor compresses refrigerant gas at a low temperature and low pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0039] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0040] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0041] An outdoor unit for an air conditioner may include an outdoor casing. An outdoor heat exchange duct may be installed inside the outdoor casing.

[0042] The outdoor casing may include an outdoor air inlet. The outdoor air inlet may be connected to an outdoor heat exchange duct. The outdoor air inlet is used to introduce outdoor air into the outdoor heat exchange duct.

[0043] The outdoor casing may include an outdoor air outlet. The outdoor air outlet may connect to an outdoor heat exchange duct. The outdoor air outlet may be used to exhaust air from inside the outdoor heat exchange duct to the outside of the outdoor heat exchange duct.

[0044] An outdoor unit of an air conditioner may include an outdoor heat exchanger. The outdoor heat exchanger may be located inside an outdoor heat exchange duct.

[0045] An outdoor unit for an air conditioner may include an outdoor fan. The outdoor fan may be installed inside an outdoor heat exchange duct.

[0046] The rotation of the outdoor fan causes outdoor air to enter the heat exchange duct through the outdoor air inlet and exchange heat with the outdoor heat exchanger. After heat exchange, the outdoor air flows out of the outdoor heat exchange duct through the outdoor air outlet.

[0047] An air conditioner may include a compressor. The compressor is located inside the outdoor heat exchange duct.

[0048] Air conditioners may include a throttling device. The throttling device is used to limit airflow. The throttling device can be provided in either the indoor or outdoor unit of the air conditioner.

[0049] Air conditioners execute a refrigeration cycle using a compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes including compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

[0050] The compressor compresses the refrigerant gas at low temperature and low pressure and discharges it at high temperature and high pressure. The discharged refrigerant gas flows into the condenser.

[0051] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0052] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0053] The evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0054] An evaporator achieves a cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0055] In the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0056] The air conditioner provided in the embodiments of the present invention can have various implementation forms.

[0057] In this embodiment, the air conditioner includes a floor-standing unit. The floor-standing unit is installed indoors and is used for heat exchange with the indoor environment.

[0058] refer to Figure 1 The cabinet unit includes a housing 1. The housing 1 has an internal cavity, and the housing 1 has an external shape that forms the overall appearance of the cabinet unit.

[0059] Continue to refer to Figure 1 The cabinet unit includes a humidification module 2, which is located inside the cavity.

[0060] Introducing a humidifier module 2 into a cabinet air conditioner will have a significant impact on the internal structural layout of the unit. In order to ensure the balance between the various modules, the humidifier module 2 needs to be innovatively designed to ensure that its introduction will not affect the operation of other modules, while also better leveraging its humidifying function.

[0061] This application provides an air conditioner that adopts an integrated humidification module 2 design, eliminating the need for a separate water tank. The overall layout is reasonable, with high space utilization, and does not affect the performance and use of other functions. By setting a float switch 204, a liquid level difference is formed between the humidification outer cover 201 and the humidification chamber 202. The water level in the humidification chamber 202 is slightly higher than the surface of the heating element 203, which improves the humidification efficiency and shortens the humidification preparation time.

[0062] refer to Figure 2 , Figure 3 As shown, the humidification module 2 includes a humidification cover 201, which is used to store water.

[0063] The aforementioned humidification module 2 adopts an integrated design, eliminating the need for a separate water tank. This results in a reasonable overall layout, high space utilization, and does not affect the performance and use of other functions.

[0064] Continue to refer to Figure 2 , Figure 3 As shown, the humidification module 2 includes a humidification chamber 202, which is fitted inside the humidification cover 201 and has a water inlet, and is connected to the humidification cover 201 through the water inlet.

[0065] The humidification module 2 of the air conditioner adopts a structure of humidification cover 201 and humidification chamber 202, with the liquid located between the humidification chamber 202 and the humidification cover 201.

[0066] refer to Figure 3 As shown, the humidification module 2 includes a heating element 203, which is disposed inside the humidification chamber 202 and is used to heat water to form humidified air.

[0067] The integrated humidifier module 2 features a design where water is added only after the humidifier module 2 is completely removed. Water is stored inside the humidifier outer cover 201, which is separated from the humidifier chamber 202. To improve humidification efficiency, a float 2044-type water level switch is used to control the water level in the humidifier chamber 202. The heating area of ​​the heating element 203 is relatively small, and this design effectively isolates heat transfer, preventing users from getting burned when removing the humidifier module 2.

[0068] refer to Figure 4 As shown, the humidification module 2 includes a float switch 204, which is installed at the water inlet to control water to enter the humidification chamber 202 from the humidification cover 201.

[0069] The aforementioned humidification module 2 adopts an integrated design, eliminating the need for a separate water tank. This results in a more rational overall layout and higher space utilization, without affecting the performance and use of other functions. Furthermore, by incorporating a float switch 204, a liquid level difference is created between the humidification outer casing 201 and the humidification chamber 202. The water level in the humidification chamber 202 is slightly higher than the surface of the heating element 203, improving humidification efficiency and shortening preparation time. Simultaneously, the float switch 204 avoids the use of commonly used one-way valves, resulting in a higher level of integration for the humidification module 2. The float switch 204 directly controls the float switch outlet 2043, blocking it when the water level reaches the required level, making operation more convenient.

[0070] refer to Figure 5 , Figure 6 , Figure 7 As shown, the float switch 204 includes a switch cavity 2041, the interior of which defines a channel, and has a float switch inlet 2042 and a float switch outlet 2043 located at both ends of the channel and communicating with the channel. The opening direction of the float switch outlet 2043 is towards the direction in which the water level in the humidification cavity 202 drops.

[0071] Continue to refer to Figure 5 , Figure 6 , Figure 7 As shown, the float switch 204 includes a float 2044; the float 2044 is disposed in the humidification chamber 202, rises as the water level in the humidification chamber 202 rises, falls as the water level in the humidification chamber 202 falls, and blocks the float switch outlet 2043 when the water level in the humidification chamber 202 is higher than the heating element 203, and moves away from the float switch outlet 2043 when the water level in the humidification chamber 202 is lower than the heating element 203 to connect the humidification outer cover 201 and the humidification chamber 202.

[0072] The humidification module 2 of the aforementioned air conditioner adopts a structure of humidification cover 201 and humidification chamber 202. Liquid is located between the humidification chamber 202 and the humidification cover 201. The water connection between the humidification chamber 202 and the liquid is controlled by a float switch 204. The float 2044 rises as the water level in the humidification chamber 202 rises and falls as the water level in the humidification chamber 202 falls. When the water level in the humidification chamber 202 is higher than the heating element 203, or slightly higher than the surface of the heating element 203, the float 2044 blocks the float switch outlet 2043, and water in the humidification cover 201 no longer flows into the humidification chamber 202. As the heating element 203 heats the surrounding water to form humidified air, the humidification... As the water level in the humidification chamber 202 decreases, the float 2044 also decreases and moves away from the float switch outlet 2043, connecting the humidification cover 201 with the humidification chamber 202. Water from the humidification cover 201 flows into the humidification chamber 202, raising the float 2044. The distance between the float 2044 and the outlet becomes smaller and smaller. When the water level in the humidification chamber 202 reaches the critical value, the water level stabilizes, and the float 2044 blocks the float switch outlet 2043 again.

[0073] In some embodiments of this application, the float switch 204 further includes a guide for limiting the range of movement of the float 2044 in the direction of rising and falling water levels.

[0074] The guide component guides the upward and downward trajectory of the float 2044, preventing positional changes caused by water fluctuations within the humidification chamber 202 that could block the float switch outlet 2043. The guide component can be a structure with an elongated groove. The float 2044 has a protrusion that fits the groove. The groove extends along the direction of water level rise and fall within the humidification chamber 202, and the protrusion, in conjunction with the groove, guides the float 2044.

[0075] In some embodiments of this application, the float 2044 is provided with a rubber 2045 adapted to block the float switch outlet 2043.

[0076] By setting a rubber 2045 that is compatible with the float switch outlet 2043, it is beneficial to improve the sealing effect of the float switch 204 on the float switch outlet 2043 during use, thereby creating a liquid level difference between the humidifying outer cover 201 and the humidifying chamber 202, so that the water level in the humidifying chamber 202 is slightly higher than the surface of the heating element 203, which improves the humidification efficiency and shortens the humidification preparation time.

[0077] In some embodiments of this application, the humidification chamber 202 is disposed near the side of the humidification cover 201.

[0078] The heating element 203 is disposed inside the humidification chamber 202, which is located on one side of the humidification cover 201. When water needs to be added, the humidification module 2 can be completely removed without touching the side where the humidification chamber 202 is located, thus preventing the user from getting burned when removing the humidification module 2. Furthermore, this arrangement also helps to isolate heat transfer, allowing the heating element 203 to heat the surrounding water more efficiently to generate humidified air, thereby improving humidification efficiency.

[0079] like Figure 8 , Figure 9 As shown, the humidification chamber 202 includes a water inlet chamber 2021 and a heating chamber 2022 connected to the water inlet chamber 2021. A water inlet is provided on the water inlet chamber 2021.

[0080] refer to Figure 2 , Figure 3 A heating element 203 is installed inside the heating chamber 2022, and the heating chamber 2022 is located on the side near the humidifying cover 201.

[0081] The humidifying chamber 202 is divided into a water inlet chamber 2021 and a heating chamber 2022 connected to the water inlet chamber 2021. The water inlet of the humidifying chamber 202 is separated from the heating element 203, preventing the heat radiated by the heating element 203 from overflowing through the water inlet of the humidifying chamber 202. This not only helps to isolate heat transfer but also avoids potential burns. At the same time, the heating chamber 2022 is located on one side of the humidifying outer cover 201, with the heating element 203 located in the heating chamber 2022. This concentrates the heating area within the heating chamber 2022. On the one hand, when water needs to be added, the side where the heating chamber 2022 is located can be avoided when the humidifying module 2 is completely removed, preventing burns to the user's hands when removing the humidifying module 2. Furthermore, this arrangement also helps to isolate heat transfer, allowing the heating element 203 to heat the surrounding water more efficiently to generate humidified air, thereby improving humidification efficiency.

[0082] refer to Figure 4 and Figure 8 The side of the water inlet chamber 2021 away from the heating chamber 2022 is provided with a humidification chamber cover 2023 for sealing the water inlet chamber 2021.

[0083] By setting the humidification chamber cover 2023, the float 2044 switch can be maintained after the humidification chamber cover 2023 is opened, which facilitates maintenance. At the same time, the humidification chamber cover 2023 is set away from the heating chamber 2022, which also helps to isolate heat transfer.

[0084] refer to Figure 4 The bottom surface of the heating cavity 2022 is provided with a heating element base 2024 for mounting the heating element 203, and the heating element base 2024 encloses the heating cavity 2022.

[0085] After opening the heating element base 2024, the heating element 203 can be directly maintained, which facilitates the maintenance of the heating element 203. At the same time, the scale is concentrated in the electric heating area inside the humidification chamber 202, which can be directly cleaned after disassembling the heating element base 2024.

[0086] The above-mentioned integrated steam humidification module 2 is designed to be easy to install and disassemble. Since there is no water tank, it is easy to clean between the humidification chamber 202 and the humidification cover 201. The installation is done by squeezing with rubber 2045, which is convenient and quick. The scale is concentrated in the electric heating area inside the humidification chamber 202. It can be cleaned directly after disassembly. The maintenance of the float 2044 can be completed by removing the humidification chamber cover 2023.

[0087] refer to Figure 4 , Figure 5 , Figure 6 The heating chamber 2022 has an air outlet on its top surface, and the housing 1 has an air outlet 101. The air outlet and the air outlet 101 are connected by a humidification pipe 205.

[0088] The heating element 203 heats the water in the heating chamber 2022, and the generated humidified air is transported through the air outlet and the humidification pipe 205, and discharged into the room through the air outlet 101 to regulate the indoor humidity.

[0089] refer to Figure 1 and Figure 10 The inner cavity includes a first cavity 102, a second cavity 103, and a third cavity 104 arranged sequentially from top to bottom along the height direction of the cabinet unit. The first cavity 102 is connected to the indoor environment through an air outlet 101.

[0090] In some embodiments of this application, the first cavity 102 and the second cavity 103 are separated by a first partition 105; the first cavity 102 is provided with a second partition 106 that divides the first cavity 102 into a mixing cavity 1021 and a fresh air cavity 1022.

[0091] In some embodiments of this application, the humidification pipe 205 passes through the first partition 105 and communicates with the mixing chamber 1021; the humidified air and part of the fresh air are mixed in the mixing chamber 1021 and then enter the room through the air outlet 101, while another part of the fresh air enters the room through the fresh air chamber 1022 and the air outlet 101.

[0092] By setting a second partition 106, the humidified air is mixed with a portion of the fresh air in the mixing chamber 1021 before being discharged, thus preventing the humidified air from mixing with the fresh air throughout the first chamber 102, which would cause a large amount of humidified vapor to condense. The humidification outlet of the humidification module 2 is located in front of the fresh air outlet, horizontally aligned with the air conditioner directly in front of it. The humidified air is mixed with a portion of the fresh air in the mixing chamber 1021 before being discharged. The humidification outlet occupies a portion of the fresh air space, leaving sufficient space for mixing with the fresh air while minimizing the impact on the fresh air volume, and ensuring that the humidification outlet is cooled to a temperature that is not too hot to the touch.

[0093] In some embodiments of this application, the second partition 106 is a bent plate bent toward the mixing chamber 1021.

[0094] The second partition 106 is a bent plate that bends toward the mixing chamber 1021. The liquid water condensed on the second partition 106 will not be carried out of the air outlet 101 with the fresh air, thus ensuring the user's experience.

[0095] Continue to refer to Figure 1 , Figure 10 The cabinet unit includes a total heat exchange module 3, which is located in the second cavity 103.

[0096] In some embodiments of this application, the cabinet unit includes a fresh air module 4, which is disposed in the third cavity 104.

[0097] In some embodiments of this application, the cabinet includes an electrical box 5, which is disposed in the third cavity 104.

[0098] The cabinet air conditioner mainly consists of the following modules. Divided by a central section, the upper part of the unit comprises the air conditioning duct and heat exchange module, while the lower part consists of a humidification module 2, a total heat exchange module 3, a fresh air module 4, and an electrical control box 5. The fresh air module 4 is integrated with the intake and exhaust design and is also connected to the total heat exchange module 3. To ensure sufficient airflow for the fresh air module 4 and to achieve a steam humidification layout that doesn't occupy space from other air conditioning modules, thus improving space utilization, the humidification module 2 is integrated into the gap in the fresh air volute. The humidification module 2 and the total heat exchange module 3 are at the same vertical height, not occupying space in the electrical control box. The space between the humidification and total heat exchange modules is reserved for wiring in the electrical control box, improving the overall integration of the cabinet air conditioner with the humidification module 2.

[0099] The humidification module design of this cabinet air conditioner utilizes the space next to the air conditioner casing. Without affecting the casing size and air conditioning piping, it makes reasonable use of a portion of the space in the panel base and rear cover to achieve convenient installation and easy maintenance of the humidification module 2.

[0100] The humidification module 2 is located in the lower middle part of the unit. The total heat exchange module 3 is level with the humidification module 2. The humidification module 2 is removed and the water is changed using a front-extraction method. The replacement of the total heat exchange module 3 is also done in the same way. The electrical box 5 is located below the two modules, horizontally placed in the middle of the machine, with about 30mm of space left on both sides and the top for cable management. This humidification layout does not affect the function of other modules and facilitates disassembly and water change operations. The integrated design eliminates the need for dedicated installation space for water tanks, making the structure more compact and space-efficient. Moreover, the compact layout hardly affects the original functions of air conditioning and fresh air systems.

[0101] Another embodiment of this application provides an air conditioner, including a cabinet unit. The cabinet unit is installed indoors for exchanging heat with the indoor environment.

[0102] refer to Figure 1 The cabinet unit includes a housing 1. The housing 1 has an internal cavity, and the housing 1 has an external shape that forms the overall appearance of the cabinet unit.

[0103] Continue to refer to Figure 1 The cabinet unit includes a humidification module 2, which is located inside the cavity.

[0104] Introducing a humidifier module 2 into a cabinet air conditioner will have a significant impact on the internal structural layout of the unit. In order to ensure the balance between the various modules, the humidifier module 2 needs to be innovatively designed to ensure that its introduction will not affect the operation of other modules, while also better leveraging its humidifying function.

[0105] This application provides an air conditioner that adopts an integrated humidification module 2 design, eliminating the need for a separate water tank. The overall layout is reasonable, with high space utilization, and does not affect the performance and use of other functions. By setting a float switch 204, a liquid level difference is formed between the humidification outer cover 201 and the humidification chamber 202. The water level in the humidification chamber 202 is slightly higher than the surface of the heating element 203, which improves the humidification efficiency and shortens the humidification preparation time.

[0106] refer to Figure 2 , Figure 3 As shown, the humidification module 2 includes a humidification cover 201, which is used to store water.

[0107] The aforementioned humidification module 2 adopts an integrated design, eliminating the need for a separate water tank. This results in a reasonable overall layout, high space utilization, and does not affect the performance and use of other functions.

[0108] Continue to refer to Figure 2 , Figure 3As shown, the humidification module 2 includes a humidification chamber 202, which is fitted inside the humidification cover 201 and has a water inlet, and is connected to the humidification cover 201 through the water inlet.

[0109] The humidification module 2 of the air conditioner adopts a structure of humidification cover 201 and humidification chamber 202, with the liquid located between the humidification chamber 202 and the humidification cover 201.

[0110] refer to Figure 3 As shown, the humidification module 2 includes a heating element 203, which is disposed inside the humidification chamber 202 and is used to heat water to form humidified air.

[0111] The integrated humidifier module 2 features a design where water is added only after the humidifier module 2 is completely removed. Water is stored inside the humidifier outer cover 201, which is separated from the humidifier chamber 202. To improve humidification efficiency, a float 2044-type water level switch is used to control the water level in the humidifier chamber 202. The heating area of ​​the heating element 203 is relatively small, and this design effectively isolates heat transfer, preventing users from getting burned when removing the humidifier module 2.

[0112] refer to Figure 4 As shown, the humidification module 2 includes a float switch 204, which is installed at the water inlet. When the water level in the humidification chamber 202 is higher than the heating element 203, the connection between the humidification cover 201 and the humidification chamber 202 is disconnected, and when the water level in the humidification chamber 202 is lower than the heating element 203, the connection between the humidification cover 201 and the humidification chamber 202 is established.

[0113] The aforementioned humidification module 2 adopts an integrated design, eliminating the need for a separate water tank. This results in a more rational overall layout and higher space utilization, without affecting the performance and use of other functions. Furthermore, by incorporating a float switch 204, a liquid level difference is created between the humidification outer casing 201 and the humidification chamber 202. The water level in the humidification chamber 202 is slightly higher than the surface of the heating element 203, improving humidification efficiency and shortening preparation time. Simultaneously, the float switch 204 avoids the use of commonly used one-way valves, resulting in a higher level of integration for the humidification module 2. The float switch 204 directly controls the float switch outlet 2043, blocking it when the water level reaches the required level, making operation more convenient.
