Description

Technical Field

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

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

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

[0004] In related technologies, steam humidification modules include a humidification chamber and a water tank. The water tank is connected to the humidification chamber to ensure a continuous water supply. A heating element is installed inside the humidification chamber to heat the water, causing it to boil and convert into steam, which is then released. However, the heat from the high-temperature steam in the humidification chamber is easily transferred to the water tank. This causes an unnecessary increase in the water temperature inside the tank, resulting in additional energy loss and reduced humidification system efficiency. Furthermore, the high temperature of the water tank poses a risk of scalding when the user removes it to refill, compromising user safety. Utility Model Content

[0005] This application discloses an air conditioner that can prevent steam heat from being conducted to the water tank through the fluid channel and the water outlet.

[0006] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0007] Cabinet unit, the cabinet unit includes:

[0008] chassis;

[0009] A humidification module, disposed within the housing, comprises:

[0010] Humidification chamber;

[0011] A heating element is disposed inside the humidification chamber, and the heating element is used to convert the water in the humidification chamber into water vapor;

[0012] A water tank is located above the humidification chamber, and the water tank has a water outlet facing the humidification chamber for adding water to the humidification chamber;

[0013] A one-way valve is connected to the water tank and located at the water outlet. The one-way valve is configured to connect the water tank and the humidification chamber after the water tank and the humidification chamber are assembled, so that the water level in the humidification chamber is maintained at a preset position.

[0014] The humidification chamber is equipped with:

[0015] A fluid channel connecting the water outlet and the heating element;

[0016] A stop portion is provided within the fluid channel and forms part of the top wall of the fluid channel. The stop portion is configured such that when fluid flows through the stop portion, the height of the top wall of the fluid channel at the stop portion is lower than the water level of the humidification chamber, so that water vapor from the heating element is blocked on the side of the stop portion away from the water outlet.

[0017] In this way, the stop section, through the principle of liquid seal barrier, confines the high-temperature steam generated by the heating element to the heating area of ​​the humidification chamber, preventing the steam heat from being conducted to the water tank through the fluid channel and water outlet. On the one hand, the water in the tank does not need to withstand the high temperature of steam, eliminating unnecessary heat loss and allowing electrical energy to be concentrated on the heating element to generate water vapor, significantly improving humidification efficiency; on the other hand, the water tank always maintains a normal temperature, completely avoiding the risk of scalding when users remove the water tank to refill it, greatly improving safety.

[0018] This application also provides an air conditioner, wherein the humidification chamber includes a first top wall, a stop portion is disposed on the first top wall, the bottom of the stop portion extends downward from the first top wall to form a second top wall, and the height of the second top wall is lower than the water level of the humidification chamber.

[0019] Thus, the second top wall formed by the extension of the first top wall makes the liquid seal structure more stable. On the one hand, the second top wall is integrally extended from the top wall of the humidification chamber without any splicing gaps, which prevents steam from leaking out of the gaps. On the other hand, the height difference between the second top wall and the water level can be precisely controlled. For example, the height of the second top wall can be designed to be 5mm-10mm lower than the preset water level, ensuring that no matter how slightly the water level in the humidification chamber fluctuates, the second top wall is always below the water level, and the liquid seal effect does not fail.

[0020] This application also provides an air conditioner, wherein the fluid channel includes a plurality of sub-channels, and two adjacent sub-channels extend along a first horizontal direction and a second horizontal direction, respectively, and the first horizontal direction and the second horizontal direction are arranged to intersect.

[0021] Thus, the intersecting sub-channels, by changing direction, not only lengthen the water flow path, making the temperature transfer slower, but also lengthen the diffusion path of water vapor from the heating element to the outlet. The steam must first diffuse along the later sub-channel to the intersection, and then turn to diffuse along the earlier sub-channel, increasing the path length.

[0022] At the same time, the sub-channels in the intersecting area and the liquid seal section of the subsequent sub-channel form a double barrier. Even if the steam breaks through the liquid seal, it will be intercepted by the side wall of the sub-channel during the turning process, further reducing the transfer of steam heat to the water tank, reducing the rise in water temperature in the water tank, reducing energy waste, and further eliminating the risk of scalding from high temperature in the water tank.

[0023] This application also provides an air conditioner, wherein the first horizontal direction and the second horizontal direction are arranged perpendicularly.

[0024] Thus, the vertical arrangement creates a longer L-shaped path than a non-vertical path, increasing the heat transfer distance from the heating element area to the water tank. This further reduces the temperature rise in the water tank, bringing it closer to ambient temperature. The vertical turn requires the steam to change its horizontal direction twice before it can diffuse towards the outlet. Each turn results in a decrease in the steam's kinetic energy. Compared to the single turn in a non-vertical arrangement, the vertical arrangement increases the rate of kinetic energy attenuation. Even if a small amount of steam breaks through the liquid seal, it will not reach the outlet due to depletion of kinetic energy, preventing heat transfer from the steam to the water tank, stabilizing the temperature of the water tank's outer wall, and eliminating the risk of scalding for users.

[0025] This application also provides an air conditioner, wherein the water outlet and the heating element are arranged along the first horizontal direction, and a plurality of the sub-channels are arranged around the outer periphery of the heating element on the side away from the water outlet.

[0026] Thus, when the outlet and the heating element are arranged along the first horizontal direction, the traditional straight water supply path is the path from the outlet to the side of the heating element closest to the outlet. However, after the sub-channels are arranged around the outer periphery of the heating element away from the outlet, the water flow path forms a combination structure of the main path and the surrounding branch path. The total path length is extended. With the path lengthened, more time is provided for water flow to dissipate heat, the uniformity of water flow temperature is improved, the heat conduction distance is increased, and the heat transferred to the water tank per unit time is reduced.

[0027] This application also provides an air conditioner, wherein the humidification chamber includes a first sidewall extending along the first horizontal direction, and the plurality of sub-channels include a first sub-channel, a plurality of second sub-channels and a plurality of third sub-channels arranged sequentially along the flow direction of the fluid, wherein the first sub-channel is arranged along the first sidewall and along the second horizontal direction, the width of the first sub-channel on the side near the water outlet is smaller than the width on the side away from the water outlet.

[0028] Thus, the gradual change in width of the first sub-channel reduces the flow velocity of the water and further extends the flow time. Combined with the diversion and circulation of the second and third sub-channels, the total cooling path length is further extended. At the same time, the first sub-channel is arranged along the first side wall, increasing the contact area with the cavity wall. The gradual change in width increases the contact area compared to channels of equal width, further improving the heat dissipation efficiency of the water flow.

[0029] This application also provides an air conditioner, wherein the heating element is located in the middle of the humidification chamber, and the humidification chamber further includes a second sidewall adjacent to the first sidewall. The second sidewall is located on the side of the heating element away from the water outlet and extends along the second horizontal direction. A plurality of second sub-channels are arranged along the second sidewall, and adjacent second sub-channels are arranged in a bent manner.

[0030] Thus, the second sub-channel is arranged along the second side wall, and the adjacent second sub-channels are arranged in a bend, so that the water flow can fully contact the second side wall during the bend and extension process, which can further absorb and release the heat conducted by steam, and prevent the temperature around the heating element from diffusing in the opposite direction to the water tank.

[0031] Moreover, the bend design of the second sub-channel extends the water flow path compared to the design without bends, further extending the total cooling path length. This increases the flow time of the water from the outlet to the heating element, thereby increasing the convective heat dissipation time and further reducing the water temperature near the water tank.

[0032] This application also provides an air conditioner, wherein the humidification chamber includes a top cover and a bottom shell, the bottom shell has a plurality of interconnected grooves, the plurality of interconnected grooves and the top cover together enclose the fluid channel, and along the flow direction of the fluid, a plurality of third sub-channels are disposed close to the heating element;

[0033] The stop portion is disposed on the top cover and is located at the top of the plurality of third sub-channels.

[0034] Thus, by machining multiple interconnected grooves on the bottom shell, the top cover covers the bottom shell and seals against the edge of the groove opening to form a closed fluid channel. The inner side of the top cover is also machined with a protruding structure that matches the stop part to ensure that the stop part is aligned with the third sub-channel.

[0035] Since the third sub-channel also has multiple segments, placing the stop at the top of multiple third sub-channels can create a multi-layer liquid seal barrier effect, further preventing steam from being conducted to the water tank through the fluid channel and water outlet, ensuring that the heat is more concentrated near the heating element and improving humidification efficiency.

[0036] This application also provides an air conditioner, wherein the cabinet unit further includes a fresh air module and an air outlet grille, the fresh air module includes a fresh air outlet, the humidification module includes a humidification outlet, and both the fresh air outlet and the humidification outlet are located at the air outlet grille.

[0037] In this way, both the fresh air outlet and the humidification outlet of the humidification module are located inside the air outlet grille, and the orientation of both outlets is consistent with the airflow direction of the grille, ensuring that the airflow can be smoothly delivered along the direction of the grille blades. The clean fresh air discharged from the fresh air outlet and the water vapor discharged from the humidification outlet are initially mixed in this cavity, and then guided by the airflow blades of the grille to form a mixed air with a suitable temperature, humidity, and sufficient oxygen content, avoiding the discomfort caused by a single fresh air or a single humidified air blowing directly on the user.

[0038] This application also provides an air conditioner, wherein the humidification outlet is located within the fresh air outlet, so that the fresh air from the fresh air outlet can drive the steam from the humidification outlet to be blown out of the air outlet grille.

[0039] Therefore, since steam tends to condense and linger near the humidification outlet when there is no fresh air intake, the humidification outlet is located inside the fresh air outlet. This allows the fresh air from the fresh air outlet to carry the steam from the humidification outlet out of the air grille. When the positive pressure airflow flows through the fresh air outlet, it creates a negative pressure zone inside. The fresh air actively draws the steam from the humidification outlet to diffuse, and the steam mixes with the fresh air inside the outlet, increasing the diffusion speed, preventing condensation and water accumulation around the humidification outlet, and avoiding mold growth.

[0040] Compared with the prior art, the beneficial effects of this application are as follows:

[0041] In this application, after the water tank is assembled, the one-way valve opens, and water flows into the fluid channel through the water tank's outlet. It then flows smoothly to the periphery of the heating element via the stop section. Since the stop section only lowers the height of the top wall of the fluid channel without blocking the water path, water replenishment can reach the heating area normally, maintaining a stable water level in the humidification chamber. When the heating element operates, it causes the surrounding water to boil, generating water vapor. Due to its lower density, the water vapor diffuses upwards. When it comes into contact with the stop section within the fluid channel, because the top wall of the flow channel at the stop section is lower than the water level in the humidification chamber, the water vapor is blocked by a liquid seal formed by the water level on the side of the stop section away from the outlet, i.e., the side where the heating element is located. It cannot flow backwards through the fluid channel to the outlet and the water tank.

[0042] In this way, the stop section, through the principle of liquid seal barrier, confines the high-temperature steam generated by the heating element to the heating area of ​​the humidification chamber, preventing the steam heat from being conducted to the water tank through the fluid channel and water outlet. On the one hand, the water in the tank does not need to withstand the high temperature of steam, eliminating unnecessary heat loss and allowing electrical energy to be concentrated on the heating element to generate water vapor, significantly improving humidification efficiency; on the other hand, the water tank always maintains a normal temperature, completely avoiding the risk of scalding when users remove the water tank to refill it, greatly improving safety.

[0043] Furthermore, the fluid channel design ensures that water replenishment from the tank flows only to the area surrounding the heating element, preventing water from spreading widely within the humidification chamber. This guarantees sufficient water around the heating element to maintain efficient steam generation while reducing water storage in non-heated areas of the humidification chamber. The fluid channel also limits the water flow direction, preventing disordered water distribution within the humidification chamber and avoiding widespread boiling caused by heat dispersion from the heating element. Even in the event of localized boiling, the liquid seal formed by the stop prevents bubbles from impacting the outlet, preventing them from overflowing into the water tank or equipment through the one-way valve channel. This protects the cabinet's electrical components from damage by high-temperature water and prevents external water leakage, ensuring a safe operating environment for users. Moreover, this application achieves its purpose simply by adding a fluid channel and stop within the humidification chamber, without requiring significant modifications to existing components such as the water tank and one-way valve. It boasts strong compatibility, directly adapting to the installation layout of existing cabinet humidification modules, reducing production modification difficulty and costs, and facilitating mass production and application.

Unless otherwise stated, "a plurality of" means two or more.

[0064] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0065] During air conditioning operation, especially in cooling or heating mode, indoor air humidity may decrease, causing people to feel dry and uncomfortable, and potentially leading to problems such as dry skin and respiratory illnesses. Therefore, air conditioners are equipped with a steam humidification module, which delivers water vapor into the room to increase indoor air humidity and improve indoor comfort.

[0066] In related technologies, steam humidification modules include a humidification chamber and a water tank. The water tank is connected to the humidification chamber to ensure a continuous water supply. A heating element is installed inside the humidification chamber to heat the water, causing it to boil and convert into steam, which is then released. However, the heat from the high-temperature steam in the humidification chamber is easily transferred to the water tank. This causes an unnecessary increase in the water temperature inside the tank, resulting in additional energy loss and reduced humidification system efficiency. Furthermore, the high temperature of the water tank poses a risk of scalding when the user removes it to refill, compromising user safety.

[0067] Based on this, the present application provides an air conditioner that can confine the high-temperature steam generated by the heating element to the heating area of ​​the humidification chamber through liquid sealing, thereby preventing the steam heat from being conducted to the water tank through the fluid channel and the water outlet.

[0068] The following will describe specific embodiments and appendices. Figure 1 To be continued Figure 10 The technical solution of the air conditioner in this application is described.

[0069] like Figures 1 to 3As shown, one embodiment of this application provides an air conditioner, which includes a cabinet unit 100. The cabinet unit 100 includes a housing 10 and a humidification module 20, with the humidification module 20 disposed inside the housing 10. The housing 10 serves as the outer shell of the entire cabinet unit 100, providing a mounting carrier for the humidification module 20 and other components, ensuring the stability of component integration, and also possessing a certain degree of decorative appeal to blend into different interior decoration styles.

[0070] like Figure 4 and Figure 5 As shown, the humidification module 20 includes a humidification chamber 21 and a heating element 22. The heating element 22 is disposed inside the humidification chamber 21 and is used to convert the water in the humidification chamber 21 into water vapor. As a core actuator, the heating element 22 is fixed inside the humidification chamber 21 and acts directly on the water in the chamber to generate water vapor.

[0071] It should be explained that when the heating element 22 works, it causes the surrounding water to boil and generate water vapor. Because the water vapor has a low density, it diffuses upward. The top of the humidification chamber 21 is connected to a humidification pipe, through which the water vapor is guided out of the cabinet 100.

[0072] The heating element 22 can be an electric heating element, or it can be a heating tube, a ceramic heating element 22, an electromagnetic induction heating element 22, or other heating elements 22. This application does not limit the specific heating element 22.

[0073] like Figure 4 As shown, the humidification module 20 also includes a water tank 23, which is located above the humidification chamber 21. The water tank 23 has a water outlet 231 facing the humidification chamber 21, which is used to add water to the humidification chamber 21. The water tank 23 is used to store water and provide a water source for the generation of water vapor. The water tank 23 replenishes water to the humidification chamber 21 through the water outlet 231 using the principle of gravity water supply.

[0074] like Figure 5 As shown, the humidification module 20 also includes a one-way valve 24, which is connected to the water tank 23 and located at the water outlet 231. The one-way valve 24 is configured to connect the water tank 23 and the humidification chamber 21 after assembly, so as to maintain the water level in the humidification chamber 21 at a preset position. The one-way valve 24 controls the water supply. When the water tank 23 and the humidification chamber 21 are assembled, the one-way valve 24 opens to connect the water path, so that the water level in the humidification chamber 21 is maintained at a preset height, which satisfies the immersion requirement of the heating element 22 and avoids overflow due to excessive water volume.

[0075] like Figure 5As shown, the humidification chamber 21 is provided with a fluid channel 211, which connects the water outlet 231 and the heating element 22. The fluid channel 211 serves as a water passage between the water outlet 231 of the water tank 23 and the heating element 22, guiding the water in the water tank 23 to the surrounding area of ​​the heating element 22. This prevents the water from spreading disorderly within the humidification chamber 21, ensuring that there is always sufficient water to be heated around the heating element 22, while also reducing the amount of ineffective water storage in non-heated areas.

[0076] like Figure 6 and Figure 10 As shown, a stop portion 212 is provided inside the fluid channel 211, and the stop portion 212 constitutes part of the top wall of the fluid channel 211. The stop portion 212 is configured such that when the fluid flows through the stop portion 212, the height of the top wall of the fluid channel 211 at the stop portion 212 is lower than the water level of the humidification chamber 21, so that the water vapor of the heating element 22 is blocked on the side of the stop portion 212 away from the outlet 231.

[0077] It should be explained that in the diagram, H represents the water level in the humidification chamber 21, and D represents the height of the stop 212. Both of these heights are measured with reference to the bottom wall of the humidification chamber 21.

[0078] Therefore, after the water tank 23 is assembled, the one-way valve 24 opens, and the water flows into the fluid channel 211 through the outlet 231 of the water tank 23. It then flows smoothly to the periphery of the heating element 22 through the area of ​​the stop part 212. Since the stop part 212 only reduces the height of the top wall of the fluid channel 211 and does not block the water path, the water can reach the heating area normally, maintaining the water level of the humidification chamber 21.

[0079] When the heating element 22 is working, it causes the surrounding water to boil and generate water vapor. Because the water vapor has a low density, it diffuses upward. When it comes into contact with the stop part 212 in the fluid channel 211, the top wall of the flow channel at the stop part 212 is lower than the water level in the humidification chamber 21. The water vapor is blocked by the liquid seal formed by the water level on the side of the stop part 212 away from the outlet 231, that is, the side where the heating element 22 is located. It cannot flow backward through the fluid channel 211 to the outlet 231 and the water tank 23.

[0080] Thus, the stop part 212, through the principle of liquid seal barrier, confines the high-temperature steam generated by the heating element 22 to the heating area of ​​the humidification chamber 21, preventing the steam heat from being conducted to the water tank 23 through the fluid channel 211 and the water outlet 231. On the one hand, the water in the water tank 23 does not need to withstand the high temperature of the steam, eliminating unnecessary heat loss and allowing electrical energy to be concentrated on the heating element 22 to generate water vapor, significantly improving humidification efficiency; on the other hand, the water tank 23 always maintains a normal temperature, completely avoiding the risk of scalding when the user removes the water tank 23 to refill it, greatly improving the safety of use.

[0081] Moreover, the design of the fluid channel 211 ensures that the water replenishment from the water tank 23 flows only to the area surrounding the heating element 22, preventing the water from spreading widely within the humidification chamber 21. This ensures that there is sufficient water around the heating element 22 to maintain efficient steam generation, while also reducing the amount of water stored in the non-heating areas of the humidification chamber 21. The fluid channel 211 limits the direction of water replenishment, preventing the water from being distributed randomly within the humidification chamber 21 and preventing large-scale boiling caused by the heat dispersion of the heating element 22. Even if local boiling occurs, the liquid seal formed by the stop part 212 can prevent water bubbles from impacting the outlet 231, preventing water bubbles from overflowing into the water tank 23 or the inside of the equipment through the one-way valve 24. This protects the electrical components of the cabinet 100 from damage by high-temperature water and also prevents water leakage from the outside of the equipment, ensuring the safety of the user's operating environment.

[0082] Furthermore, this application achieves this simply by adding a fluid channel 211 and a stop 212 inside the humidification chamber 21, without requiring significant modifications to existing components such as the water tank 23 and the one-way valve 24. It is highly compatible and can be directly adapted to the installation layout of the existing cabinet air conditioner 100 humidification module 20, reducing the difficulty and cost of production modification and facilitating mass promotion and application.

[0083] In the diagram, the X direction is the first horizontal direction, the Y direction is the second horizontal direction, and the Z direction is the vertical direction.

[0084] In some embodiments, such as Figure 6 and Figure 10 As shown, the humidification chamber 21 includes a first top wall 213, a stop 212 disposed on the first top wall 213, the bottom of the stop 212 extends downward from the first top wall 213 to form a second top wall 214, and the height of the second top wall 214 is lower than the water level of the humidification chamber 21.

[0085] It should be explained that in the diagram, H is the water level in the humidification chamber 21, and D is the height of the second top wall 214, that is, the height of the stop part 212.

[0086] Thus, the first top wall 213 is the original top wall of the humidification chamber 21, forming the main closed structure of the upper part of the humidification chamber 21, while providing the top boundary for the fluid channel 211, ensuring the overall sealing and structural stability of the channel, and preventing water or steam from leaking from the top of the channel to other areas of the humidification chamber 21.

[0087] Furthermore, the stop portion 212 extends from the first top wall 213 toward the interior of the humidification chamber 21 to form a protruding structure. The end of its extension constitutes the second top wall 214. The height of the second top wall 214 is lower than the preset water level of the humidification chamber 21 and lower than the height of the first top wall 213. When the preset water level is maintained in the humidification chamber 21, the second top wall 214 is completely below the water level. At this time, the fluid channel 211 in the area of ​​the stop portion 212 is completely covered by water, forming a liquid seal section. The fluid channel 211 in this area is completely filled with water, and steam cannot penetrate the water. It can only be restricted to the side of the second top wall 214 away from the outlet 231, completely blocking the diffusion path of steam to the outlet 231 and the water tank 23.

[0088] Therefore, the second top wall 214 formed by the extension of the first top wall 213 makes the liquid seal structure more stable. On the one hand, the second top wall 214 is integrally extended from the top wall of the humidification chamber 21 without splicing gaps, which avoids steam leakage from gaps. On the other hand, the height difference between the second top wall 214 and the water level can be precisely controlled. For example, the height of the second top wall 214 can be designed to be 5mm-10mm lower than the preset water level, ensuring that no matter how slightly the water level in the humidification chamber 21 fluctuates, the second top wall 214 is always below the water level, and the liquid seal effect does not fail.

[0089] The stop portion 212 may be a protruding structure additionally designed on the inner wall of the first top wall 213, or the stop portion 212 may be formed by a concave structure on the surface of the first top wall 213 facing the interior of the humidification chamber 21. This application does not limit it here.

[0090] In some embodiments, such as Figure 7 and Figure 8 As shown, the fluid channel 211 includes multiple sub-channels 2111, with two adjacent sub-channels 2111 extending along a first horizontal direction and a second horizontal direction, respectively, and the first horizontal direction and the second horizontal direction intersecting each other.

[0091] Thus, the intersecting sub-channels 2111 not only lengthen the water flow path by changing direction, making the temperature transfer slower, but also lengthen the diffusion path of water vapor from the heating element 22 to the outlet 231. The steam needs to diffuse along the rear sub-channel 2111 to the intersection first, and then turn to diffuse along the front sub-channel 2111, increasing the path length.

[0092] At the same time, the sub-channel 2111 in the intersecting area and the liquid seal section of the subsequent sub-channel 2111 form a double barrier. Even if the steam breaks through the liquid seal, it will be intercepted by the side wall of the sub-channel 2111 during the turning process, further reducing the transfer of steam heat to the water tank 23, reducing the rise in water temperature of the water tank 23, reducing energy waste, and further eliminating the risk of high temperature burns from the water tank 23.

[0093] In other embodiments, when the distance between the heating element 22 and the outlet 231 of the water tank 23 is far, a single straight channel can also be used.

[0094] In some embodiments, such as Figure 8 As shown, the first horizontal direction and the second horizontal direction are arranged perpendicularly.

[0095] Thus, the vertical arrangement forms a longer L-shaped path than a non-vertical path, increasing the heat transfer distance from the high temperature of the heating element 22 region to the water tank 23. This further reduces the temperature rise of the water in the water tank 23, bringing it closer to ambient temperature. The vertical turn requires the steam to change its horizontal direction twice to diffuse towards the outlet 231. Each turn results in a decrease in the steam's kinetic energy. Compared to the single turn in a non-vertical arrangement, the steam's kinetic energy attenuation rate is increased in the vertical arrangement. Even if a small amount of steam breaks through the liquid seal, it will not reach the outlet 231 due to the depletion of its kinetic energy, preventing heat transfer from the steam to the water tank 23, stabilizing the temperature of the outer wall of the water tank 23, and eliminating the risk of scalding for users.

[0096] In some embodiments, such as Figure 8 As shown, the outlet 231 and the heating element 22 are arranged along the first horizontal direction, and multiple sub-channels 2111 are arranged around the outer periphery of the heating element 22 on the side away from the outlet 231.

[0097] Thus, when the outlet 231 and the heating element 22 are arranged along the first horizontal direction, the traditional straight water supply path is the path from the outlet 231 to the side of the heating element 22 closest to the outlet 231; however, after the sub-channel 2111 is arranged around the outer periphery of the heating element 22 away from the outlet 231, the water flow path forms a combination structure of the main path and the surrounding branch path, the total path length is extended, and the increased path length provides more time for water flow to dissipate heat, improves the uniformity of water flow temperature, increases the heat conduction distance, and reduces the heat transferred to the water tank 23 per unit time.

[0098] In some embodiments, such as Figure 7 As shown, the humidification chamber 21 includes a first sidewall 215 extending along a first horizontal direction, and a plurality of sub-channels 2111 including a first sub-channel 2111a, a plurality of second sub-channels 2111b and a plurality of third sub-channels 2111c arranged sequentially along the flow direction of the fluid. The first sub-channel 2111a is arranged along the first sidewall 215. Along the second horizontal direction, the width of the first sub-channel 2111a on the side near the water outlet 231 is smaller than the width on the side away from the water outlet 231.

[0099] It should be explained that in the diagram, d2 is the width of the side of the first sub-channel 2111a closest to the outlet 231, and d1 is the width of the side of the first sub-channel 2111a furthest from the outlet 231.

[0100] Thus, the first sub-channel 2111a is arranged along the first side wall 215, with one end connected to the outlet 231 of the water tank 23 and the other end connected to the second sub-channel 2111b. It extends along the first horizontal direction and is the initial guiding section for water to enter the humidification chamber 21. Multiple second sub-channels 2111b are connected to the first sub-channel 2111a at one end and extend into the humidification chamber 21 at the other end, which is the diversion and transition section for water flow. Multiple third sub-channels 2111c are arranged around the outer periphery of the heating element 22 away from the outlet 231, with one end connected to the second sub-channel 2111b and the other end covering the periphery of the heating element 22, which is the final water supply section for water flow.

[0101] The gradual width change of the first sub-channel 2111a reduces the flow velocity of the water and further extends the flow time. Combined with the diversion and circulation of the second sub-channel 2111b and the third sub-channel 2111c, the total cooling path length is further extended. At the same time, the first sub-channel 2111a is arranged along the first side wall 215, increasing the contact area with the cavity wall. The gradual width change increases the contact area compared to a channel with equal width, further improving the heat dissipation efficiency of the water flow.

[0102] In some embodiments, such as Figure 8 As shown, the heating element 22 is located in the middle of the humidification chamber 21. The humidification chamber 21 also includes a second sidewall 216 adjacent to the first sidewall 215. The second sidewall 216 is located on the side of the heating element 22 away from the water outlet 231 and extends along the second horizontal direction. Multiple second sub-channels 2111b are arranged along the second sidewall 216, and adjacent second sub-channels 2111b are arranged in a bent manner.

[0103] Thus, the second sub-channel 2111b is arranged along the second side wall 216, and the adjacent second sub-channels 2111b are arranged in a bent manner, so that the water flow can fully contact the second side wall 216 during the bending and extension process, which can further absorb and release the heat conducted by steam, and prevent the temperature around the heating body 22 from diffusing in the opposite direction to the water tank 23.

[0104] Moreover, the bend design of the second sub-channel 2111b extends the water flow path compared to the non-bend design, further extending the total cooling path length. This increases the flow time of the water from the outlet 231 to the heating element 22, increasing the convective heat dissipation time and further reducing the water temperature near the water tank 23.

[0105] The second sub-channel 2111b can be formed by three second sub-channels 2111b bending into each other, or by four, five or more bends, etc., and this application does not limit it here.

[0106] In some embodiments, such as Figure 5As shown, the humidification chamber 21 includes a top cover 217 and a bottom shell 218. The bottom shell 218 has multiple interconnected grooves 2181. The multiple interconnected grooves 2181 and the top cover 217 together form a fluid channel 211. Along the flow direction of the fluid, multiple third sub-channels 2111c are arranged close to the heating element 22.

[0107] In some embodiments, such as Figure 10 As shown, the stop portion 212 is disposed on the top cover 217 and is located on top of the plurality of third sub-channels 2111c.

[0108] Thus, by machining multiple interconnected grooves 2181 on the bottom shell 218, the top cover 217 covers the bottom shell 218 and seals against the groove edge of the groove 2181 to form a closed fluid channel 211. The inner side of the top cover 217 is also machined with a protruding structure that matches the stop part 212 to ensure that the stop part 212 is aligned with the third sub-channel 2111c.

[0109] Since the third sub-channel 2111c also has multiple segments, the stop part 212 is located at the top of the multiple third sub-channels 2111c, which can form a multi-layer liquid seal barrier effect, further preventing steam from being conducted to the water tank 23 through the fluid channel 211 and the outlet 231, ensuring that the heat is more concentrated near the heating element 22 and improving the humidification efficiency.

[0110] The top cover 217 and the bottom shell 218 can be sealed by a sealing ring or by welding, which is not limited here.

[0111] In some embodiments, such as Figure 1 As shown, the cabinet unit 100 also includes a fresh air module and an air outlet grille 11. The fresh air module includes a fresh air outlet, and the humidification module 20 includes a humidification outlet. Both the fresh air outlet and the humidification outlet are located at the air outlet grille 11.

[0112] Thus, the fresh air module is integrated inside the casing 10 of the cabinet unit 100, usually near the side wall or back of the cabinet unit 100, to facilitate the introduction of outdoor fresh air. The fresh air module includes a fresh air inlet for connecting to the outside, as well as a fresh air fan, an air filter unit and a fresh air outlet. The fresh air module drives outdoor air through the fresh air fan to filter the air through the filter screen to form clean fresh air, which is finally delivered to the air outlet grille 11 area through the fresh air outlet.

[0113] Both the fresh air outlet and the humidification outlet of the humidification module 20 are located inside the air outlet grille 11. The orientation of both the fresh air outlet and the humidification outlet is consistent with the air guide direction of the air outlet grille 11, ensuring that the airflow can be smoothly delivered along the direction of the air guide blades. The clean fresh air discharged from the fresh air outlet and the water vapor discharged from the humidification outlet are initially mixed in this cavity, and then guided by the air guide blades of the air outlet grille 11 to form a mixed air with a suitable temperature, qualified humidity and sufficient oxygen content, avoiding the discomfort caused by a single fresh air or a single humidified air blowing directly on the user.

[0114] In some embodiments, the humidification outlet is located inside the fresh air outlet, so that the fresh air from the fresh air outlet can drive the steam from the humidification outlet out of the air outlet grille 11.

[0115] Since steam tends to condense and linger near the humidification outlet when there is no fresh air intake, the humidification outlet is located inside the fresh air outlet. This allows the fresh air from the fresh air outlet to carry the steam from the humidification outlet out of the air outlet grille 11. When the positive pressure airflow flows through the fresh air outlet, a negative pressure zone is formed inside. The fresh air actively draws the steam from the humidification outlet to diffuse. The steam and fresh air mix inside the outlet, increasing the diffusion speed, preventing condensation and water accumulation around the humidification outlet, and avoiding mold growth.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
