Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a ceiling-mounted central humidifying device. Background Art

[0002] Central humidifiers are household appliances commonly used in people's daily lives, and central humidifiers installed on the ceiling are widely promoted and used because of their strong humidification capacity. Central humidifiers are usually installed in the ceiling in a hidden way, supplied with tap water (some manufacturers require water purifiers or water softeners), and sent air to various areas of the house through air ducts, achieving one-stop humidification of the whole house.

[0003] Chinese patent publication number CN 113028541A ​​discloses a humidification device, which is equipped with a humidification module to humidify the air flowing through it, and in order to supply water to the humidification module, a water sprinkling module is additionally configured to spray water on the top to supply water to the humidification module. During use, due to water pressure fluctuations, the water supply of the water sprinkling module is likely to change, and more water is concentrated and overflows into the water tank, which cannot evenly wet the wet membrane; at the same time, the water on the top of the wet membrane assembly is prone to uneven distribution, causing the wet membrane to not be evenly wetted, which in turn leads to poor humidification effect.

[0004] In view of this, how to design a technology that can conveniently control the water supply flow rate and improve the wetting uniformity of the wet film to improve the humidification effect is the technical problem to be solved by the present invention. Summary of the invention

[0005] The present invention provides a ceiling-mounted central humidifying device, which can conveniently control the water supply flow of the ceiling-mounted central humidifying device and improve the wetting uniformity of the wet film, so as to improve the humidification effect.

[0075] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0076] The ceiling-mounted central humidification equipment adopts wet film technology. Water is transported to the wet film to make the wet film as a whole moist. After the air enters the ceiling-mounted central humidification equipment, the moist wet film is used to humidify the air flowing through it.

[0077] like Figure 1-Figure 3 As shown, this embodiment provides a ceiling-mounted central humidification device, including:

[0078] The housing 1 is provided with an air inlet 101 and an air outlet 102, and a mounting socket 103 is also provided on the side wall of the housing 1;

[0079] A humidifying module 2, the humidifying module 2 comprises a water tank 21, a wet membrane assembly 22 and a drainage pump 23, the wet membrane assembly 22 is arranged in the water tank 21, and the drainage pump is arranged in the water tank 21 and is used to drain the water in the water tank 21;

[0080] The water spray module 3 is provided with a plurality of water spray holes 301 for discharging water downwards;

[0081] The electric control module 4 is provided with an electric control board 41 .

[0082] During assembly, the humidification module 2 is inserted into the housing 1 from the installation socket 103. The humidification module 2 divides the interior of the housing 1 into an air inlet cavity and an air outlet cavity. The air inlet 101 is connected to the air inlet cavity, and the air outlet 102 is connected to the air outlet cavity. The watering module 3 is installed in the housing and located above the humidification module 2. The electric control module 4 is also installed on the housing 1 and controls the operation of the electrical components inside the ceiling-mounted central humidification device through the electric control board 41. For example, the electric control board 41 is electrically connected to the drainage pump to control the operation of the drainage pump.

[0083] During use, the water spraying module 3 sprays water onto the humidification component in the humidification module 2 below through the water spraying hole 301, and the airflow entering the shell 1 from the water inlet is humidified by the humidification component when passing through the humidification component, thereby increasing the humidity of the airflow, and finally the airflow is output to the outside from the air outlet 102 to adjust the indoor ambient humidity.

[0084] Embodiment 1, as Figure 3-Figure 4 As shown, in order to meet the requirements of compact design of the overall equipment structure, effectively shorten the length of the overall equipment, facilitate disassembly and maintenance to reduce the difficulty and cost of maintenance, the structural layout of each module inside the housing 1 is improved and designed, specifically: the wet membrane assembly 22 is arranged along the length direction of the water tank 21, and the electric control module 4 and the drainage pump are arranged side by side with the wet membrane assembly 22 along the width direction of the water tank 21.

[0085] Specifically, the wet membrane assembly 22, the drainage pump and the electric control module 4 are all arranged in the housing 1, and the electric control module 4, the wet membrane assembly 22 and the drainage pump are arranged along the width direction of the housing 1, so that the width direction of the housing 1 can be fully utilized to install each module.

[0086] On the one hand, the electronic control module 4 is integrated into the interior of the shell 1 to fully utilize the internal space of the shell 1 for installation. On the other hand, the drainage pump is arranged on one side of the wet membrane assembly 22 along the width direction, reducing the overall length of the humidification module 2, thereby reducing the overall length of the ceiling-mounted central humidification equipment as a whole.

[0087] In this way, when installing at the user's home, the problem of difficult installation due to limited length and increased difficulty in subsequent maintenance can be better solved.

[0088] By embedding the electronic control module in the shell, the additional length of the electronic control module outside the shell can be reduced. In addition, inside the shell, the electronic control module, the wet membrane assembly and the drainage pump are arranged along the width direction of the shell, and the width direction of the shell can be fully utilized to arrange related components inside the shell, thereby minimizing the overall length of the ceiling-mounted central humidification equipment, thereby facilitating the on-site installation of the ceiling-mounted central humidification equipment.

[0089] In some embodiments of the present application, the wet membrane assembly 22 is sandwiched between the electronic control module 4 and the drainage pump. The electronic control module 4 is located on one side of the air inlet 101 , and the drainage pump is located on one side of the air outlet 102 .

[0090] Specifically, in order to more reasonably plan the layout of internal components, the electronic control module 4, the wet membrane assembly 22 and the drainage pump are arranged in sequence along the width direction of the outer shell 1. The overall shape of the electronic control module 4 is arranged relatively regularly at the air inlet 101 to reduce interference with the air inlet side and improve the smoothness of the air flow.

[0091] In another embodiment of the present application, the humidification module 2 is inserted into the housing 1 from the mounting socket 103, and its exposed end needs to be connected, fixed and locked with the housing 1. For this purpose, an end cover 24 is provided at one end of the water tank 21, and a handle 25 is provided on the end cover 24.

[0092] Specifically, after the humidification module 2 is inserted into the housing 1 through the installation socket 103 , the end cover 24 will be against the outer wall of the housing 1 and cover the installation socket 103 , and then the end cover 24 is fixedly connected to the housing 1 by hand-tightening bolts.

[0093] When the humidification module 2 needs to be disassembled, the hand-tightened bolts are removed, and the humidification module 2 is pulled out of the housing 1 by pulling the handle 25 .

[0094] In another embodiment, since the electric control module 4 is integrated inside the housing 1, it occupies the internal space of the housing 1 and thus easily affects the air intake. In order to increase the air intake of the whole machine, an air guide plate 5 is also provided in the air intake cavity. The air guide plate 5 is located between the air inlet 101 and the humidification module 2. The air guide plate 5 is configured to guide the airflow entering from the air inlet 101 to flow to the wet membrane assembly 22.

[0095] Specifically, the electric control module 4 is located in the air inlet cavity, and the drainage pump is located in the air outlet cavity; the air guide plate 5 is arranged in the air inlet cavity to guide the airflow introduced by the air inlet 101. Under the action of the air guide plate 5, the airflow introduced by the air inlet 101 is guided to flow toward the wet film assembly 22. The air guide plate 5 guides the airflow flow to reduce the random flow of the airflow in the housing 1, thereby reducing the wind resistance caused by other components inside the housing 1 to the airflow, and finally achieving an increase in the air intake of the whole machine.

[0096] In some embodiments, in order to facilitate the installation and arrangement of the air guide plate 5, one end of the air guide plate 5 is arranged below the air inlet 101, and the air guide plate 5 is arranged to extend upward from the air inlet 101 to the wet membrane assembly 22 in an inclined manner.

[0097] Specifically, one end of the air guide plate 5 is arranged below the air inlet 101 , and the air guide plate 5 as a whole is inclined upward and extends toward the wet membrane assembly 22 , so that the inclined air guide plate 5 can better guide the airflow entering from the air inlet 101 to flow toward the wet membrane assembly 22 .

[0098] In some embodiments, both sides of the air guide plate 5 are respectively provided with folded edge structures 51 bent upward.

[0099] Specifically, in the process of guiding the airflow through the air guide plate 5, the folding structure 51 is distributed on both sides of the air guide plate 5, and the airflow can be further guided by the folding structure 51 to block the airflow from flowing to the outside of the air guide plate 5, so that the airflow introduced from the air inlet 101 can flow to the humidification component to the maximum extent, thereby improving the air supply efficiency.

[0100] In the second embodiment, during the process of airflow passing through the wet membrane component 22, the water spraying module 3 on the top needs to spray water and humidify the wet membrane component 22 below. However, since a certain gap is formed between the water spraying module 3 and the wet membrane component 22, the airflow can be blown to the top of the wet membrane component 22 through the gap, thereby affecting the water distribution on the top of the wet membrane component 22, especially the water falling on the top of the wet membrane component 22 will be blown to the corners, thereby causing the water film to not be evenly humidified.

[0101] In order to solve the above problems, Figure 8-Figure 14 As shown, a recessed structure 223 is provided on the top of the mounting frame 221, and a plurality of first water inlet holes 224 are provided in the recessed structure 223. The first water inlet holes 224 are configured to divert water from above the wet film 222 to the middle area of ​​the wet film 222. An annular retaining rib 225 is also provided in the recessed structure 223, and the annular retaining rib 225 surrounds the outside of the first water inlet.

[0102] Specifically, the recessed structure 223 is located below the water sprinkling module 3, and the water sprayed downward by the water sprinkling module 3 will fall into the recessed structure 223, while the recessed structure 223 covers the top of the mounting frame 221. In this way, during the water sprinkling process, even if the descending water flow is blown by the air flow, too much water will not be blown out into the air outlet cavity.

[0103] More importantly, the multiple first water inlet holes 224 set on the top plate 2212 of the mounting frame 221 are arranged in the middle area, and the multiple first water inlet holes 224 are surrounded by the annular retaining ribs 225, so that the water sprayed by the spray module 3 is first accumulated in the space surrounded by the annular retaining ribs 225, and the annular retaining ribs 225 are used to block the airflow to ensure that the water accumulated in the annular retaining ribs 225 can effectively flow into the wet film 222 below the flow channel of the first water inlet holes 224.

[0104] The water supplied by the first water inlet hole 224 is distributed in the middle of the wet membrane 222, and the amount of water is sufficient so that the wet membrane 222 can diffuse moisture outward from the middle, thereby uniformly humidifying the water membrane.

[0105] By arranging a recessed structure on the top of the mounting frame, the recessed structure can collect water sprinkled by the sprinkler module, and an annular retaining rib arranged around the first water inlet hole is also provided in the recessed structure. The annular retaining rib can form an independent area, so that the water falling into it can flow to the wet film below through the first water inlet hole, so that the middle area of ​​the wet film can obtain sufficient water supply to better soak the entire wet film. The cooperation between the recessed structure and the annular retaining rib can effectively reduce the influence of airflow on uneven water distribution, so that the wet film can be evenly humidified to optimize the humidification effect and improve the humidification efficiency.

[0106] In some embodiments, the edges of both ends of the recessed structure 223 are respectively provided with second water inlet holes 226 , and the second water inlet holes 226 are configured to guide water from above the wet film 222 to the end regions of the wet film 222 .

[0107] Specifically, in order to better and evenly humidify the wet film 222, a second water inlet hole 226 is also provided in the recessed structure 223. The second water inlet hole 226 is arranged at the edge of the recessed structure 223. The water sprayed by the water spraying module 3 falls into the recessed structure 223. The water located on the outside of the annular retaining rib 225 will flow to the second water inlet hole 226 at the end of the recessed structure 223 under the action of the airflow. The second water inlet hole 226 will drain the water to the end face of the wet film 222. The water will infiltrate the interior from the end of the wet film 222, and cooperate with the water supply of the first water inlet hole 224 to ensure that the inside and outside of the wet film 222 are sufficiently and evenly supplied with water.

[0108] Embodiment three, as Figure 8-Figure 14As shown, for the humidification module 2, it is necessary to install the wet film assembly 22 and the drainage pump on the water tank 21. In order to facilitate the operator to assemble, the water tank 21 includes a main tank body 211 and a sub-tank body 212, and the main tank body 211 and the sub-tank body 212 are connected to each other; the main tank body 211 is extended along the length direction of the outer shell 1, and the sub-tank body 212 is arranged on one side of the main tank body 211 along the width direction of the outer shell 1; wherein, the wet film assembly 22 is arranged in the main tank body 211, and the drainage pump is arranged above the sub-tank body 212.

[0109] Specifically, for the humidification module 2 , the water tank 21 configured therein is divided into a main tank body 211 and a sub-tank body 212 that are interconnected, wherein the sub-tank body 212 is arranged on the side of the end of the main tank body 211 to form an L-shaped tank structure.

[0110] For easy installation, the wet membrane assembly 22 is clamped into the main tank 211, and the drainage pump is installed above the auxiliary tank 212. In this way, when assembling the wet membrane assembly 22, the effect of the drainage pump installation position on the space during the assembly of the wet membrane assembly 22 can be reduced.

[0111] In order to facilitate the clamping configuration, the two ends of the wet membrane assembly 22 are respectively provided with first connecting claws 2201 , and the two ends of the main tank body 211 are respectively provided with second connecting slots 2111 .

[0112] Specifically, when the wet membrane assembly 22 is assembled into the main tank body 211, the wet membrane assembly 22 is placed into the main tank body 211, and the width and length directions of the main tank body 211 evenly match the length and width dimensions of the wet membrane assembly 22, so that the wet membrane assembly 22 can be matched and tightly inserted into the main tank body 211.

[0113] After the wet membrane 222 is fully pressed into the main tank body 211 and assembled in place, the first connection claw will be clamped in the second connection clamping groove 2111 to realize the clamping of the wet membrane assembly 22 and the main tank body 211 together. No additional auxiliary connection components are required for connection, which is more conducive to rapid on-site assembly.

[0114] By configuring connecting claws at both ends of the wet membrane assembly, the water tank is designed as two tank bodies accordingly, and a connecting slot cooperating with the connecting claws is provided in the main tank body. The wet membrane assembly is conveniently installed in the main tank body by a card-mounted manner. In addition, the drain pump is arranged and installed on the auxiliary tank body to reduce the spatial impact of the drain pump on the installation of the wet membrane assembly, thereby reducing the assembly difficulty of the humidification module and improving the assembly efficiency.

[0115] In some embodiments, the humidification module 2 includes a plurality of wet membrane assemblies 22 , and the plurality of wet membrane assemblies 22 are sequentially arranged side by side along the length direction of the main tank body 211 .

[0116] Specifically, in order to reduce the length of a single wet membrane assembly 22, a plurality of wet membrane assemblies 22 are inserted into the main tank body 211 to meet the requirements of airflow humidification.

[0117] Among them, the wet membrane assembly 22 includes a mounting frame 221 and a wet membrane 222, the wet membrane 222 is arranged in the mounting frame 221, and the two ends of the mounting frame 221 are respectively provided with a first connecting claw and a first connecting groove 2202; among them, two adjacent wet membrane assemblies 22, the first connecting claw on one wet membrane assembly 22 is clamped in the first connecting groove on the other wet membrane assembly 22; in addition, the first connecting claw of the wet membrane assembly 22 located at the outermost end is clamped in the second connecting groove 2111 at the corresponding end.

[0118] Specifically, during the assembly process, multiple wet membrane assemblies 22 are placed in the main tank body 211, wherein two adjacent wet membrane assemblies 22 cooperate with each other through the first connection claw and the first connection slot to realize the assembly and clamping of two adjacent wet membranes 222. At the same time, the outermost wet membrane assembly 22 is clamped and connected with the second connection slot 2111 through the first connection claw, and finally, a secure connection between the multiple wet membrane assemblies 22 is realized and the multiple wet membrane assemblies 22 are clamped in the main tank body 211 as a whole.

[0119] In another embodiment, in order to facilitate the assembly of the wet film assembly 22, the mounting frame 221 includes a base frame 2211, a top plate 2212, two hollow frames 2213 and two vertical plates 2214, the two vertical plates 2214 are arranged on the corresponding ends of the base frame 2211, the hollow frames 2213 are arranged on the corresponding sides of the base frame 2211, the two hollow frames 2213 and the two vertical plates 2214 are connected to form a side enclosure, the top plate 2212 is arranged on the top of the side enclosure, and the vertical plate 2214 is provided with a first connecting claw and a first connecting groove.

[0120] Specifically, the installation frame 221 adopts a split design. The two relatively arranged hollow frames 2213 can restrict the wet film 222 in the installation frame 221 on the one hand, but on the other hand, the hollow frames 2213 do not meet the requirements of airflow in and out.

[0121] In order to facilitate assembly, first slots 22111 are provided on both sides of the base frame 2211, second slots 22141 are provided on both sides of the vertical plate 2214, a first insertion strip 22131 is provided at the bottom of the hollow frame 2213, and a second insertion strip 22132 is provided at the end of the hollow frame 2213. The first insertion strip is inserted into the first slot 22111, and the second insertion strip is inserted into the second slot; the top plate 2212 is clamped on the two vertical plates 2214.

[0122] Specifically, during the installation frame assembly process, the bottom of the hollow frame 2213 is plugged into the bottom frame 2211 through the first insertion strip and the first slot 22111, and then the two sides of the hollow frame 2213 are connected to the vertical plate 2214 through the second insertion strip and the second slot. The wet film 222 is then placed between the two hollow frames 2213, and finally the top plate 2212 is covered on the top of the vertical plate 2214 and the hollow frame 2213 to complete the assembly of the wet film assembly 22.

[0123] The two ends of the top plate 2212 are respectively provided with second connection claws 22122 extending downward, and the vertical plate 2214 is provided with a third connection slot 22142. The second connection claw is located on the outer side of the vertical plate 2214 on the corresponding side and is clamped in the third connection slot.

[0124] Specifically, when the top plate 2212 is finally installed, the two ends of the top plate 2212 are locked and fixed by cooperating with the second connecting claws and the third connecting slots, so that the overall assembly of the wet membrane component 22 is a screw-free design. On the one hand, it reduces the difficulty and efficiency of assembly due to the reduction of screw assembly, and on the other hand, it saves the use of screws to avoid the screws being soaked in water and rusting in the later stage, thereby improving the reliability of use.

[0125] In addition, the two sides of the top plate 2212 are respectively provided with ribs 22121 extending downwards, and the ribs 22121 are located on the outer sides of the hollow frame 2213 on the corresponding sides.

[0126] Specifically, the hollow frames 2213 on both sides can be positioned and limited by the retaining edges 22121, so that the hollow frames 2213 on both sides are restricted between the two retaining edges 22121, so as to improve the assembly reliability.

[0127] In order to assemble the top plate 2212 more securely, a tongue 22123 is provided at the lower end of the second connecting claw, and an auxiliary slot 22143 is provided on the vertical plate 2214. The auxiliary slot is located below the third connecting slot, and the tongue is inserted into the auxiliary slot.

[0128] Specifically, when assembling the top cover, the top plate 2212 can be guided to move downward by first engaging the inserting tongue with the auxiliary slot, so that the second connecting claw can be more accurately inserted into the third connecting slot 22142 .

[0129] Meanwhile, in another embodiment, in order to improve versatility, at least one first slot 22111 is further provided in the middle of the base frame 2211 , and at least one second slot is further provided in the middle of the vertical plate 2214 .

[0130] Specifically, for wet films 222 of different thicknesses, an additional hollow frame 2213 may be placed in the installation frame 221 to meet the installation requirements of wet films 222 of different thicknesses and improve versatility of use.

[0131] In another embodiment, in order to facilitate the installation of the drainage pump, a hanging bracket 241 is provided on the end cover 24 , and the drainage pump is arranged on the hanging bracket 241 .

[0132] Specifically, the drainage pump is suspended above the auxiliary tank body 212 , and the drainage pump is fixedly installed through a suspension bracket 241 .

[0133] The suspension bracket 241 includes a fixing portion 2411 and a hanging portion 2412, wherein the fixing portion 2411 is fixedly arranged on the end cover 24, the hanging portion 2412 extends laterally, and the drainage pump is arranged on the hanging portion 2412. The fixing portion 2411 can be fixed on the end cover 24 by means of screws, and the hanging portion 2412 extends laterally to the top of the auxiliary tank body 212, so that the drainage pump is suspended above the auxiliary tank body 212.

[0134] The suspension bracket 241 may be formed into a fixing portion 2411 and a suspension portion 2412 by bending sheet metal. In order to reduce vibration noise generated by the operation of the drainage pump, a shock-absorbing pad 2413 is disposed between the drainage pump and the suspension portion 2412 .

[0135] Embodiment 4, as Figure 5 , Figure 8-Figure 14 As shown, for the humidification module 2, since water needs to be stored in the water tank 21, and after the water in the water tank 21 reaches a certain water level, it needs to be drained out through a drainage pump, for this reason, a first water level detector 26 is provided in the water tank 21. However, in actual use, it is easy for the first water level detector 26 to detect a fault and fail to start the drainage pump in time, thereby causing the water in the water tank 21 to overflow into the housing 1 and finally overflow into the room.

[0136] In order to better improve the reliability of the use of the ceiling-mounted central humidification equipment and reduce the overflow of water in the water tank 21 into the housing 1 and out of the housing 1 due to the failure of water level monitoring. The ceiling-mounted central humidification equipment also includes a water receiving tray 6; the water receiving tray 6 is arranged in the housing 1 and is located below the humidification module 2, and a second water level detector 61 is arranged in the water receiving tray 6. The water receiving tray 6 is also provided with a drain pipe 62, and the drain pipe 62 extends to the outside of the housing 1; wherein the drain pump is configured to discharge the water in the water tank 21 into the water receiving tray 6.

[0137] Specifically, during the assembly process, the water receiving tray 6 is also installed in the housing 1 so that the water receiving tray 6 is located below the humidification module 2 , wherein the lower projection of the humidification module 2 will be entirely located in the water receiving area formed by the water receiving tray 6 .

[0138] In actual use, the watering module 3 sprays water to the humidifying module 2 below, and the excess water flowing down from the wet membrane assembly 22 accumulates in the water tank 21. When the water level in the water tank 21 reaches the set upper limit height value, the first water level detector 26 will send a signal to the electric control board 41 to control the drainage pump to start drainage through the electric control board 41. The drainage pump is powered on and starts to drain the water in the water tank 21 into the water receiving tray 6 below, until the first water level detector 26 detects that the water level reaches the set lower limit height value, and then the drainage pump is controlled by the electric control board 41 to stop working.

[0139] However, when the first water level detector 26 fails or the drainage pump fails, the water in the water tank 21 cannot be drained out in time by the drainage pump. At this time, as the water level in the water tank 21 continues to rise, the water in the water tank 21 will overflow from the edge. Since the water tank 21 is located above the water receiving tray 6, the water overflowing from the water tank 21 enters the water receiving tray 6, and the overflowing water is collected by the water receiving tray 6 and discharged from the drain pipe 62.

[0140] By arranging a water receiving tray in the shell, and the water receiving tray is arranged below the humidification module, during normal use, the water sprinkled by the water sprinkling module falls on the wet membrane component of the humidification module to humidify the air flowing through, and the excess water accumulates in the water tank. When the water in the water tank reaches the set water level, the first water level detector will detect the water level to trigger the start of the drain pump, and the water in the water tank is pumped into the water receiving tray through the drain pump, and the water in the water receiving tray is finally discharged from the drain pipe. Even if the first water level detector is damaged, the water overflowing from the water tank can be collected by the water receiving tray below, and the overflow of the water tank is prevented from leaking out of the shell, thereby improving the reliability of the central humidification device to reduce leakage and thus improve the user experience.

[0141] In one embodiment of the present application, since a water receiving tray 6 is arranged at the bottom of the humidification module 2, in order to better support the humidification module 2 above, a supporting component 63 may be further provided in the water receiving tray 6, wherein the water tank 21 rests against the top of the supporting component 63, and the drain pump is configured to discharge the water in the water tank 21 into the water receiving tray 6.

[0142] Specifically, by setting a support member 63 in the water receiving tray 6, the support member 63 is used to support and guide the upper humidification module 2. In this way, when the humidification module 2 is installed, the humidification module 2 is inserted into the housing 1 from the installation socket 103, and the bottom of the humidification module 2 is supported and guided by the support member 63 to slide.

[0143] In some embodiments, two supporting components 63 arranged in parallel are provided on the water receiving tray 6, and the supporting component 63 includes a mounting component 631 and a guide component 632. The mounting component 631 is arranged in the water receiving tray 6, and the guide component 632 is arranged on the mounting component 631. The guide component 632 extends along the length direction of the water receiving tray 6; the water trough 21 is slidably arranged on the guide component 632 and is configured to slide back and forth along the length direction of the guide component 632.

[0144] Specifically, the support component 63 is fixedly installed in the water receiving tray 6 by the mounting component 631, and the guide component 632 is supported in the water receiving tray 6 by the mounting component 631. The support component 63 supports and guides the humidification module 2 inserted into the housing 1, so as to guide the humidification module 2 to slide into the inner wall of the housing 1.

[0145] In actual use, the guide component 632 is used for guiding, which can, on the one hand, enable the humidification module 2 to be assembled smoothly and accurately, and on the other hand, enable the humidification module 2 to be further supported by the water receiving tray 6 .

[0146] In another embodiment, the humidification module 2 is provided with a sliding component 27 at the bottom of the water tank 21 . The sliding component 27 extends along the length direction of the water receiving tray 6 . The sliding component 27 is configured to abut against the guide component 632 to support the water tank 21 to slide back and forth along the guide component 632 .

[0147] Specifically, in order to facilitate the support and guidance of the humidification module 2, a sliding component 27 is arranged at the bottom of the water tank 21 to cooperate with the supporting component 63 in the water receiving tray 6 to achieve sliding guidance and support installation.

[0148] In some embodiments, a vertically arranged guide plate 633 is provided on the side of the guide component 632 , and a sliding limit space is formed between the two guide plates 633 , and the sliding limit space is configured to limit the water tank 21 from sliding between the two guide plates 633 .

[0149] Specifically, after the humidification module 2 is inserted into the housing 1 from the mounting socket 103, the sliding component 27 at the bottom of the water tank 21 slides smoothly onto the guide component 632 under the action of the guide plates 633 on both sides. In addition, the guide plates 633 can further limit the shaking of the sliding component 27 on the left and right sides, so that the sliding component 27 can slide smoothly along the guide component 632.

[0150] In addition, during use, the guide plate 633 can also limit the sliding component 27 to prevent the humidification module 2 from shaking due to the influence of airflow, so as to improve the assembly reliability.

[0151] The end of the guide plate 633 toward the installation socket 103 forms an outer folded edge (not marked), and the guide component 632 extends downwardly and obliquely toward the end of the installation socket 103 .

[0152] Specifically, a bell-mouth structure is formed between the outer folded edges of the two guide plates 633 , so that the humidification module 2 can slide into the inner side of the guide plate 633 more easily and accurately on the guide component 632 .

[0153] In another embodiment, in order to increase the service life, the support component 63 further includes a wear-resistant component 634 . The wear-resistant component 634 is disposed on the guide surface formed by the guide component 632 , and the sliding component 27 abuts against the wear-resistant component 634 .

[0154] Specifically, since the sliding component 27 will slide relative to the guide component 632 during the process of disassembling and assembling the humidification module 2, the sliding process will cause friction between the two components on the one hand, and generate noise on the other hand. By arranging the wear-resistant component 634 on the guide component 632, the wear-resistant component 634 can be made of wear-resistant material to protect the guide component 632 and reduce its wear. In addition, the wear-resistant material has a low noise characteristic (such as polyetheretherketone), thereby reducing the noise generated by sliding friction.

[0155] The wear-resistant component 634 is a plate-shaped structure as a whole, and the wear-resistant component 634 is detachably disposed on the guide component 632 .

[0156] Specifically, the plate-shaped wear-resistant component 634 covers the upper part of the guide component 632, and the wear-resistant component 634 can be replaced and repaired as needed. For example, a claw is provided on the wear-resistant component 634, and a slot that cooperates with the claw is provided on the guide component 632. The wear-resistant component 634 is clamped on the guide component 632 by the claw being clamped in the slot.

[0157] The wear-resistant component 634 is mounted on the guide component 632 by using a claw and a slot. During later maintenance and replacement, the wear-resistant component 634 can be removed from the guide component 632 by simply releasing the connection between the claw and the slot.

[0158] In addition, in order to ensure secure clamping and fixing, the clamping claw includes a first clamping claw 6341 and a second clamping claw 6342, a first clamping groove 6321 is provided on the edge of the guide part 632, and a second clamping groove 6322 is provided on the side wall of the guide part 632. The first clamping claw is arranged horizontally and vertically and clamped in the first clamping groove, and the second clamping claw is arranged vertically and clamped in the second clamping groove.

[0159] Specifically, during the assembly process, the first claw is clamped in the first groove configured on the edge of the guide component 632 to achieve upper positioning and fixation, while the second claw is clamped in the second groove set on the side wall of the guide component 632 to achieve positioning and fixation of the wear-resistant component 634 distributed on the side of the guide component 632.

[0160] In another embodiment, a sealing component 64 is further provided in the water receiving tray 6 , and the sealing component 64 extends along the length direction of the water receiving tray 6 . The sealing component 64 is configured to abut against the side of the sliding component 27 after the humidification module 2 is assembled into the housing 1 .

[0161] Specifically, after the humidification module 2 is inserted into the outer shell 1, the interior of the outer shell 1 is divided into an air inlet cavity and an air outlet cavity. In order to reduce the airflow in the air inlet cavity from passing over the humidification module 2 and directly entering the air outlet cavity, the sliding component 27 on the windward side of the humidification module 2 can be sealed by the sealing component 64 configured in the water receiving tray 6 to block the airflow in the air inlet cavity from flowing into the air outlet cavity from the gap at the bottom of the humidification module 2, so as to improve the humidification efficiency.

[0162] Among them, for the two parallel sliding components 27 provided at the bottom of the water tank 21 , the sealing component 64 is in contact with the sliding component 27 adjacent to the air inlet 101 .

[0163] In addition, the longitudinal section of the sealing component 64 is a C-shaped structure. The sealing component 64 is arranged on the inner wall of the water receiving tray 6 . The sealing component 64 forms two upper and lower strip-shaped sealing contact portions, and at least one of the strip-shaped sealing contact portions contacts the sliding component 27 .

[0164] Specifically, the sealing component 64 with a C-shaped longitudinal section can achieve sealing by closely contacting the sliding component 27 through the strip-shaped sealing contact portion formed at its edge.

[0165] In some embodiments, the outer wall of the water receiving tray 6 is further provided with a heat-insulating layer (not marked), and the heat-insulating layer is arranged on the bottom and the outer peripheral side wall of the water receiving tray 6 .

[0166] Specifically, by wrapping the water receiving tray 6 with a heat-insulating layer, the heat-insulating layer is used to achieve thermal isolation between the water receiving tray 6 and the housing 1, thereby reducing condensation at the bottom of the housing 1 caused by the low water temperature in the water receiving tray 6.

[0167] Embodiment 5: For the electric control module 4, it is built in the housing 1. In order to achieve the design requirement of compact structure, the following structural design is performed for the electric control module 4.

[0168] like Figure 3 , Figure 4 and Fig. 20As shown, the electric control module 4 includes a cover shell 42 and an electric control board 41. The two sides of the cover shell 42 are respectively provided with bent mounting plates 43. The mounting plates 43 are arranged on the inner wall of the outer shell 1. An electrical cavity is formed between the cover shell 42 and the outer shell 1. The electric control board 41 is arranged on the cover shell 42 and is located in the electrical cavity.

[0169] Specifically, the electric control module 4 cooperates with the housing 1 through the cover 42 to form a relatively independent electrical cavity, and the electric control board 41 is installed in the electrical cavity. Since there is no need to configure an independent electrical box, the electric control module 4 and the housing 1 are effectively integrated to achieve a compact structure design.

[0170] By setting the cover of the electric control module inside the shell, an electrical cavity is formed between the cover and the interior of the shell, so that the electric control board is arranged in the electrical cavity to be isolated from external devices. Since the electric control module is built into the shell as a whole, on the one hand, the overall structure is more compact, which is more conducive to reducing the overall volume of the central humidifier. On the other hand, the cables connected to the electric control board are connected to related electrical components through the internal wiring of the shell, thereby avoiding damage caused by the cables exposed to the outside of the shell. By integrating the electric control module inside the shell, the compact structure design of the central humidifier is realized and the reliability of use is improved.

[0171] In some embodiments, in order to facilitate wiring, a wire threading hole 44 is provided on one of the mounting plates 43 , and the cables connected to the electric control board 41 extend to the outside of the electrical cavity through the wire threading hole 44 .

[0172] Specifically, the cables connected to the electric control board 41 extend to the outside of the electrical cavity through the wire holes 44 provided on the mounting plate 43 to be connected to external electrical components.

[0173] A wiring baffle 45 is also provided on the mounting plate 43 provided with the wire threading hole 44 , and a wiring channel is formed between the wiring baffle 45 and the mounting plate 43 , and the cables are extended along the wiring channel toward the lower bottom plate of the housing 1 for wiring.

[0174] Specifically, the cables led out from the electrical cavity are shielded and protected by the wiring baffle 45, so that the cables can be extended along the wiring baffle 45, and the cables are prevented from being lifted up due to the influence of their own stress when being led out from the threading hole 44.

[0175] In some embodiments, in order to facilitate operators to repair the electric control board 41, an inspection port 104 may be provided on the side wall of the housing 1. The inspection port 104 is connected to the electrical cavity, and a detachable electrical box cover 105 is also provided on the inspection port 104.

[0176] Specifically, by providing an inspection port 104 on the side wall of the housing 1 , when maintenance is needed, the electrical box cover 105 is removed from the inspection port 104 , and maintenance operations can be performed on the electrical control board 41 in the electrical cavity.

[0177] In one embodiment, the electric control module 4 further includes a wind pressure switch 46 , which is disposed on the cover 42 and outside the electrical cavity. The wind pressure switch 46 is arranged on one side of the air inlet 101 , and is electrically connected to the electric control board 41 .

[0178] Specifically, the wind pressure switch 46 is installed by using the cover 42, thereby saving the need for an additional independent installation support in the housing 1, making the internal structure more compact. The cover 42 is arranged in the air inlet cavity, and the cover 42 is arranged on one side of the air inlet 101, and the cover 42 serves as a mounting member to support the wind pressure switch 46.

[0179] In another embodiment, the electric control module 4 further includes a first temperature sensor 47 and a humidity sensor 48 , the temperature sensor and the humidity sensor are electrically connected to the electric control board 41 , respectively, and the temperature sensor and the humidity sensor are arranged on one side of the air inlet 101 .

[0180] Specifically, the air flow temperature and humidity of the air inlet 101 are detected by configuring a first temperature sensor 47 and a humidity sensor 48 at the air inlet 101 to facilitate humidification and temperature control. An auxiliary bracket 49 is provided on the housing 1, and the auxiliary bracket is located on one side of the air inlet 101, and the temperature sensor and the humidity sensor are provided on the auxiliary bracket.

[0181] Embodiment 6: In order to further adjust the air outlet temperature, Figure 3 , Figure 7 , Fig.24 and Fig.25 As shown, an auxiliary heating component 7 may also be configured. The auxiliary heating component 7 is disposed between the air inlet 101 and the humidification module 2 . The auxiliary heating component 7 is configured to heat the air introduced into the air inlet 101 .

[0182] Specifically, the auxiliary heating assembly 7 includes a fixed bracket 71, an electric heating component 72 and a heat dissipation fin 73. The fixed bracket 71 is surrounded by a vent (not marked), the heat dissipation fin 73 is set on the fixed bracket 71 and arranged in the vent, the electric heating component 72 is thermally connected to the heat dissipation fin 73, and the fixed bracket 71 is set on the upper top plate of the outer shell 1 and is located between the air inlet 101 and the humidification module 2.

[0183] During actual use, the airflow introduced by the air inlet 101 will flow toward the vent. Since the vent is provided with the heat dissipation fins 73, the wind resistance generated by the heat dissipation fins 73 to the airflow is small, which can meet the requirement of smooth airflow.

[0184] When the airflow needs to be heated, the electric control board 41 controls the electric heating component 72 to be powered on for heating, and the heat generated by the electric heating component 72 is transferred to the heat dissipation fins 73, so that the airflow passing through the heat dissipation fins 73 is efficiently heated.

[0185] By arranging vents on the fixed bracket and arranging heat dissipation fins in the vents, the heat generated by the electric heating component is transferred to the heat dissipation fins for heat dissipation, and the air entering the shell from the air inlet will flow to the humidification module through the vents. When the air needs to be heated, the electric heating component is energized to generate heat, and the heat generated by the electric heating component is transferred to the heat dissipation fins, so that the heat dissipation fins can be used for heat exchange with the air flowing through. The heat dissipation fins effectively increase the contact area with the air, thereby increasing the heat exchange area between the humidification device and the air to improve the heating efficiency.

[0186] In some embodiments, the top of the fixing bracket 71 is fixedly disposed on the upper top plate 11 , mounting seats 74 are disposed on both sides of the fixing bracket 71 , and the heat dissipation fins 73 are disposed between the two mounting seats 74 .

[0187] Specifically, in order to facilitate the installation of the heat dissipation fins 73 , mounting seats 74 are arranged on both sides of the fixing bracket 71 , the vent is located between the two mounting seats 74 , and the heat dissipation fins 73 are straddling the vent through the mounting seats 74 .

[0188] The mounting seat 74 is provided with a slot (not marked), and the end of the heat dissipation fin 73 is inserted into the slot on the corresponding side.

[0189] In addition, the electric heating component 72 may be an electric heating tube, a PTC heating rod, etc. The electric heating component 72 is in a long strip structure, and the end of the electric heating component 72 is inserted into the slot on the corresponding side, which is convenient for installing and fixing the electric heating component 72, and makes the electric heating component 72 more firmly attached to the heat dissipation fins 73 to ensure good heat conduction.

[0190] In some embodiments, in order to guide the airflow through the fixed bracket 71, an upper guide plate 75 may be provided on the fixed bracket 71. The upper guide plate 75 extends toward the air inlet 101 and is provided at the upper part of the vent.

[0191] Specifically, the upper guide plate 75 is arranged at the upper part of the vent, and can guide the airflow to pass through the vent below under the action of the upper guide plate 75 to improve the heat exchange efficiency.

[0192] Similarly, a lower guide plate 76 may be further provided on the fixed bracket 71 . The lower guide plate 76 extends toward the humidification module 2 . The lower guide plate 76 is provided at the upper portion of the vent.

[0193] Specifically, for the airflow output from the vent, the lower guide plate 76 is used to guide the airflow to blow upward toward the wet membrane assembly 22 to improve the air supply efficiency.

[0194] Embodiment 7: Since the ceiling-mounted central humidification equipment is composed of several components, in order to facilitate modular and rapid assembly at the factory stage, a complete shell is not used as the assembly basis, but a modular split design is implemented, as follows.

[0195] like Figure 3-Figure 7 As shown, the housing 1 includes an upper top plate 11, a lower bottom plate 12 and a surrounding plate, the surrounding plate is arranged between the lower bottom plate 12 and the upper top plate 11, and the surrounding plate includes a front panel 13, a rear panel 14, a first side vertical plate 15 and a second side vertical plate 16. The front panel 13, the second side vertical plate 16, the rear panel 14 and the first side vertical plate 15 are connected in sequence.

[0196] In order to meet the requirements of modular assembly, the following modular design is carried out:

[0197] The upper top plate 11 and the sprinkler module 3 are pre-assembled to form an upper cover module, the rear panel 14 is provided with an air inlet flange 17 to form a rear cover module, the front panel 13 is provided with an air outlet flange 18 to form a front cover module, the lower base plate 12, the first side vertical plate 15, the second side vertical plate 16, the humidification module 2, and the electronic control module 4 are independently installed; wherein, the first side vertical plate 15 is provided with a mounting socket 103.

[0198] The upper top plate 11 is arranged above the lower bottom plate 12, the front panel 13 and the rear panel 14 are arranged relatively to each other and arranged between the upper top plate 11 and the lower bottom plate 12, the first side vertical plate 15 is arranged between the upper top plate 11, the lower bottom plate 12 and the front panel 13, an inspection port 104 is formed between the first side vertical plate 15 and the rear panel 14, the second side vertical plate 16 is arranged between the upper top plate 11, the lower bottom plate 12, the front panel 13 and the rear panel 14, the humidification module 2 is inserted into the installation socket 103 and is located below the watering module 3, and the cover shell 42 is arranged between the first side vertical plate 15 and the rear panel 14.

[0199] Specifically, in the actual assembly process, the upper cover module, the rear cover module, the front cover module, the humidification module 2 and the electric control module 4 are pre-assembled in a modular manner. On the assembly bus, the operator installs the rear cover module, the front cover module, the first side stand 15 and the second side stand 16 on the lower base plate 12 to complete the installation of the main supporting components, and then installs the upper cover module on the top.

[0200] The rear cover module and the front cover module are mainly connected to the lower base plate 12 through the front panel 13 and the rear panel 14. The entire assembly process is convenient and simple. Similarly, the upper cover module is mainly connected to the front panel 13, the rear panel 14 and the two side panels through the upper top plate 11, thereby effectively reducing the time and process for assembling on-site components into the housing 1.

[0201] By pre-assembling different functional components and functional modes with the plates forming the outer shell to form a modular design, when the entire device is assembled, it is only necessary to connect the various plates that make up the shell on site. In this way, there is no need to perform on-site assembly inside the outer shell, which can effectively reduce the difficulty of assembly and facilitate operators to quickly assemble various modules on site to form a ceiling-mounted central humidification device, thereby improving assembly efficiency.

[0202] In another embodiment, the upper cover module can further integrate the auxiliary heating component 7 on the upper top plate 11, so that the upper cover module integrates multiple functional modules, which is more conducive to reducing the number of on-site workers installing them into the outer shell 1 one by one, thereby reducing the difficulty of assembly.

[0203] Embodiment 8: During the use of the user, the wet membrane assembly 22 in the humidification module 2 needs to be regularly maintained, and for this purpose, the humidification module 2 needs to be disassembled from the housing 1. In actual installation, there is a small lateral space on the top of the user's home, which will increase the difficulty of pulling out the humidification module 2 from the installation socket 103 during the later maintenance of the humidification module 2. In order to solve the problems of poor maintenance convenience and high maintenance difficulty, the following structural improvements are made.

[0204] like Figure 6 As shown, the lower bottom plate 12 is detachably disposed at the lower portion of the enclosure, the water receiving tray 6 is disposed on the lower bottom plate 12 , and the water tank 21 is detachably disposed on the end cover 24 .

[0205] Specifically, during actual use, when the humidification module 2 needs to be maintained, in addition to pulling the humidification module 2 out of the housing 1 through the installation socket 103, the water tank 21 and the wet membrane assembly 22 can also be removed from the housing 1 separately from the bottom of the housing 1.

[0206] When it is necessary to disassemble and maintain the shell 1 from the bottom, the lower base plate 12 is removed from the enclosure to expose the humidification module 2 inside the shell 1, and then the water tank 21 is removed separately from the cover plate. At this time, the wet membrane assembly 22 will be removed independently along with the water tank 21, while the drain pump is still fixedly connected to the end cover 24 on the shell 1.

[0207] By setting a mounting socket on the enclosure of the shell, the humidification module can be pulled out from the mounting socket as a whole to meet the requirements of replacing and maintaining the wet membrane assembly. At the same time, in the case of limited lateral operating space, the lower base plate of the shell can be removed from the enclosure, and then the water tank connected to the wet membrane assembly can be removed separately from the end cover to meet the requirements of replacing and maintaining the wet membrane assembly. In this way, the maintenance method can be selected according to needs without being restricted by the installation space, thereby improving the maintenance convenience of the humidifier and reducing the difficulty of maintenance.

[0208] In some embodiments, in order to facilitate the disassembly and assembly of the water tank 21 , a mounting bracket 28 is provided on the end cover 24 . The mounting bracket 28 is disposed on the inner surface of the end cover 24 , and the sliding component 27 is detachably mounted on the mounting bracket 28 .

[0209] Specifically, by providing a mounting bracket 28 on the end cover 24, the mounting bracket 28 protrudes from the inner surface of the end cover 24, so as to facilitate connection with the mounting bracket 28 from the bottom of the water tank 21 through the sliding member 27. The connection method can be a detachable method such as screws.

[0210] For example, the mounting bracket 28 is provided with a transversely extending mounting surface, the sliding component 27 is provided with a mounting hole, the mounting surface is provided with a connecting hole, and the fastening screw passes through the mounting hole from below and is threadedly connected in the connecting hole.

[0211] In some embodiments, since a water receiving tray 6 is also provided under the humidification module 2, for the water receiving tray 6, in order to facilitate disassembly and assembly, one edge of the water receiving tray 6 can be connected to the front panel 13, and the other edge of the water receiving tray 6 can be connected to the fixed bracket 71 in the auxiliary heating assembly 7.

[0212] Specifically, in the actual assembly process, the water tray 6 is fixedly connected to the front panel 13 and the lower part of the fixing bracket 71 by screws. When the humidification module 2 needs to be maintained, the lower bottom plate 12 and the water tray 6 are first removed, and then the water tank 21 is removed from the end cover 24.

[0213] One end of the air guide plate 5 is arranged on the rear panel of the enclosure and is located below the air inlet 101 , and the other end of the air guide plate 5 is overlapped on the edge of the water receiving tray 6 and is clamped between the air guide plate 5 and the fixing bracket 71 .

[0214] In another embodiment, in order to facilitate the disassembly of the lower base plate 12, the lower base plate 12 adopts a split design, that is, the lower base plate 12 includes a first base plate 121 and a second base plate 122, the first base plate 121 is close to the air inlet 101 and is located below the electronic control module 4, the second base plate 122 is close to the air outlet 102 and is located below the water tray 6, the first base plate 121 and the second base plate 122 are respectively detachably arranged at the lower part of the enclosure, and the second base plate 122 is overlapped below the first base plate 121.

[0215] Specifically, when the humidification module 2 needs to be maintained, it is only necessary to remove the second bottom plate 122 from the housing 1, and then the water receiving tray 6 and the water tank 21 can be removed in turn, without removing the entire lower bottom plate 12, which is more conducive to reducing the difficulty of disassembly and maintenance.

[0216] Embodiment 9: During use, condensation is easily generated inside and outside the housing due to temperature difference, and when the condensation accumulates on the housing to a certain extent, condensation water will drip into the user's home, resulting in a poor user experience. In order to solve the above technical problems, the housing 1 is improved as follows.

[0217] like Figure 3 Figure 5 and Figure 7 As shown, the ceiling-mounted central humidification equipment also includes an insulation component 8, which includes a first insulation component 81 and a second insulation component 812. The first insulation component 81 is a plate-mounted structure, and the second insulation component 82 is a strip structure. The first insulation component 81 is arranged on the upper top plate 11 and / or the lower bottom plate 12, and the second insulation component 82 is arranged on the enclosure below the air outlet 102.

[0218] Specifically, the first heat-insulating member 81 is in the form of a heat-insulating plate structure and is laid flat on the lower bottom plate 12 and the upper top plate 11 , thereby performing heat-insulating treatment on the upper and lower surfaces of the outer shell 1 to reduce the formation of condensation on the outer surface of the outer shell 1 .

[0219] The second heat-insulating member 82 is disposed below the air outlet 102 and covers the connection between the enclosure and the lower bottom plate 12.

[0220] By arranging an insulation component in the shell, the first insulation component can insulate the upper top plate and the lower bottom plate of the shell, thereby reducing the condensation effect of the airflow inside the shell on the upper top plate and the lower bottom plate, so as to reduce the generation of condensed water. In addition, the second insulation component will further insulate the lower part of the air outlet. On the one hand, the second insulation component can reduce the condensation generated in the enclosure area at the air outlet, and on the other hand, it can further seal the connection between the lower bottom plate and the enclosure at the air outlet to reduce the occurrence of air leakage, thereby reducing the condensation generated on the shell surface of the central ceiling-type central humidification equipment to improve the user experience.

[0221] In some embodiments, the second thermal insulation component 82 covers the connection portion formed between the enclosure and the lower base plate 12, and the upper surface of the second thermal insulation component 82 forms a guide surface 821, which extends downwardly at an angle from the air inlet 101 to the air outlet 102, and the guide surface is configured to guide water to flow into the water receiving tray.

[0222] Specifically, for the second heat-insulating member 82, the guide surface formed on its upper surface can guide the condensed water formed at the air outlet 102 to flow to the water receiving tray 6 below through the guide surface. The inclined guide surface effectively guides the condensed water to reduce the condensed water from flowing to the outside of the housing 1.

[0223] The guide surface is provided with a plurality of guide grooves 822, which extend downwardly along the direction from the air inlet 101 to the air outlet 102. The inclined guide grooves can better collect condensed water and allow the condensed water to be quickly discharged into the water receiving tray 6 under the guidance of the guide grooves 822.

[0224] In some embodiments, for the second heat-insulating component 82, an extension portion 823 is provided on its upper portion, and the free end of the extension portion extends to above the water receiving tray 6, and a guide surface is formed on the extension portion.

[0225] Specifically, the second heat-insulating member 82 forms an extension portion 823 at the upper portion so that the edge of the extension portion can extend above the water receiving tray 6 , thereby allowing the condensed water guided from the guide surface to flow reliably into the water receiving tray 6 .

[0226] In some embodiments, the first heat-insulating member 81 disposed on the upper top plate 11 is further provided with a groove, and the groove is configured to accommodate a water pipe of the shower module 3 .

[0227] Specifically, the groove formed by the first heat-insulating member 81 can accommodate the water pipe of the water-spraying module 3 , thereby facilitating the arrangement and positioning of the water channel.

[0228] In one embodiment of the present application, the insulation assembly 8 includes a third insulation component 83, which is a plate-mounted structure and is arranged on the side of the enclosure. The surface structure of the third insulation component 83 matches the outer contour of the corresponding end of the humidification module 2.

[0229] Specifically, the enclosure is provided with a third heat-insulating member 83 to achieve heat-insulating treatment of the side wall, so as to reduce the formation of condensed water in the side wall area of ​​the outer shell 1 .

[0230] At the same time, the surface of the third thermal insulation component 83 forms a surface structure that matches the outer contour of the corresponding end of the humidification module 2. In this way, after the humidification module 2 is assembled in place, the end face of the humidification module 2 can be more closely attached to the third thermal insulation component 83 to reduce the size of the gap between the two, thereby reducing the airflow passing through the gap between the two, which is more conducive to improving the humidification efficiency.

[0231] Embodiment 10: Affected by the installation method of the humidification module 2, one end of the humidification module 2 is fixed to the side wall of the housing 1 through the end cap 24, while the other end is suspended. In actual use, on the one hand, the humidification module 2 is easily vibrated and noisy inside the housing 1 by the airflow, and on the other hand, the humidification module 2 is easily shaken in the housing 1 during transportation and damaged. In order to solve the above technical problems, the installation structure of the humidification module 2 is improved as follows.

[0232] like Figure 3-Figure 5 As shown, a limiting space is also provided on the enclosure, and the limiting space is arranged opposite to the installation socket 103 ; the limiting space is configured to limit the end of the humidification module 2 inserted through the installation socket 103 .

[0233] Specifically, after the humidification module 2 is assembled in place, the end of the humidification module 2 will be located in the limiting space, and the end of the humidification module 2 will be limited by the limiting space, so that after the humidification module 2 is assembled, both ends are effectively restricted to reduce its shaking.

[0234] The limiting space is configured to limit the movement of the humidification module 2 along the width and height directions of the housing 1. Specifically, the limiting space is used to limit the position movement of the humidification module 2 in the width and height directions, so that the humidification module 2 does not shake up and down and forward and backward.

[0235] As for the limiting space, its entity can be a limiting groove formed on the enclosure, and the end of the humidification module 2 is located in the limiting groove to form the limiting space.

[0236] Alternatively, in some embodiments, two limiting components 19 are provided on the enclosure, and a limiting space is formed between the two limiting components 19, and the end of the sliding component 27 cooperates with the corresponding supporting component 63 for limiting.

[0237] Specifically, after the humidification module 2 is inserted into the housing 1 , the corresponding end of the sliding component 27 will be located between the two limiting components 19 to be limited by the limiting components 19 .

[0238] The limiting component 19 has a first limiting portion 191 and a second limiting portion 192, the first limiting portion 191 is arranged vertically, the second limiting portion 192 is arranged horizontally, the first limiting portion 191 is located outside the sliding component 27, and the second limiting portion 192 is located above the sliding component 27. The two oppositely arranged first limiting portions 191 will limit the forward and backward movement of the two sliding components 27, and at the same time, the second limiting portion 192 will limit the upward shaking of the sliding component 27.

[0239] In addition, in order to enable the sliding component 27 to be accurately inserted into the semi-enclosed structure formed by the first limiting portion 191 and the second limiting portion 192, the free end of the first limiting portion 191 is provided with a first limiting guide portion 193 bent toward the outside, and the free end of the second limiting portion 192 is provided with a second limiting guide portion 194 bent upward.

[0240] In another embodiment, the third heat-insulating member 83 is provided with an avoidance hole (not marked) matching the limiting component 19 , and the limiting component 19 passes through the avoidance hole.

[0241] Embodiment 11: Since different water sprinkling holes are located at different positions from the water inlet of the water sprinkling module 3, the water output of the water sprinkling holes at different positions is different, resulting in poor humidification effect. To solve the above technical problems, the following improved design is made for the water sprinkling module 3.

[0242] like Figure 15-19 As shown, the water sprinkling module 3 includes a water inlet valve 32 and a water sprinkling device, and the water sprinkling device 31 includes a lower water sprinkling plate 311, an upper cover plate 312 and a water inlet pipe 313. A plurality of water sprinkling holes 301 are arranged on the lower water sprinkling plate 311 along the length direction, and the upper cover plate 312 is arranged on the lower water sprinkling plate 311. A water inlet cavity is formed between the upper cover plate 312 and the lower water sprinkling plate 311. The water sprinkling holes 301 are connected to the water inlet cavity, and the water inlet pipe 313 is also connected to the water inlet cavity; wherein, an annular boss 314 corresponding to the water sprinkling hole 301 is arranged on the lower water sprinkling plate 311, and the annular boss 314 surrounds the periphery of the water sprinkling hole 301, and the water inlet pipe 313 is connected to the water inlet valve 32.

[0243] Specifically, an annular boss 314 is provided around each of the water sprinkling holes 301 on the lower water sprinkling plate 311, so that after the water inlet pipe 313 injects water into the water inlet cavity, the water level in the water inlet cavity exceeds the annular boss 314, and the water flows into the area surrounded by the annular boss 314 before being discharged from the water sprinkling holes 301. In this way, the different water outputs of the water sprinkling holes 301 at different positions caused by the different distances between the water sprinkling holes 301 and the water inlet pipe 313 can be effectively reduced. By providing the annular boss 314 around the water sprinkling holes on the lower water sprinkling plate 311, water is evenly distributed to the water sprinkling holes 301 at various positions, thereby improving the uniformity of water distribution of the water sprinkling module 3, thereby optimizing the humidification effect and improving the humidification efficiency.

[0244] By arranging annular bosses around each water sprinkling hole on the lower water sprinkling plate, the water level in the water inlet cavity will flow into the corresponding water sprinkling hole only after it is higher than the annular boss and finally spray the humidification module below. In this way, the water sprinkling holes distributed at different positions on the lower water sprinkling plate can evenly distribute water, thereby achieving uniform water sprinkling on the humidification module below, improving the uniformity of water sprinkling distribution of the water sprinkling module, optimizing the humidification effect and improving the humidification efficiency.

[0245] In some embodiments, a buffer groove 315 cooperating with the annular boss 314 is further provided on the upper cover plate 312 . The buffer groove 315 is provided above the annular boss 314 at a corresponding position, and a gap is formed between the buffer groove 315 and the annular boss 314 .

[0246] Specifically, the buffer groove 315 forms a concave space to meet the requirement that the annular boss 314 protrudes upwards, and on the other hand, the buffer groove 315 can also buffer the impact of water flow so that each water hole 301 can discharge water evenly.

[0247] In another embodiment, a water storage cavity with a U-shaped cross-section is formed between the upper cover plate 312 and the lower sprinkler plate 311 .

[0248] Specifically, a strip groove (not marked) is provided on the water sprinkling plate, the water sprinkling hole 301 is arranged at the bottom of the strip groove, the upper cover plate 312 forms a lower convex structure (not marked), the lower convex structure is arranged in the strip groove, and a water storage cavity is formed between the lower convex structure and the strip groove. The U-shaped water storage cavity can reduce its water storage capacity, so that the water entering the water inlet pipe 313 can quickly fill the U-shaped water storage cavity, and then quickly discharge water out through the water sprinkling hole 301.

[0249] In order to facilitate the assembly of the water shower 31, an annular rib 316 is provided around the strip groove on the lower water shower plate 311, and an annular slot 317 is provided around the lower convex structure on the upper cover plate 312, and the annular rib 316 is inserted into the annular slot 317. The annular rib 316 is inserted into the annular slot 317 to realize the assembly of the lower water shower plate 311 and the upper cover plate 312, and the annular rib 316 can be bonded in the annular slot 317 to improve the sealing performance.

[0250] In addition, the water inlet pipe 313 and the lower water spraying plate 311 are an integrated structure, which is convenient for injection molding. In addition, for easy installation and fixing, the two ends of the lower water spraying plate 311 are also provided with connecting plates 318, which can be fixed on the upper top plate 11 of the housing 1 by screws.

[0251] Based on the above technical solution, optional, such as Figure 26-Figure 28As shown, the top surface of the wet film forms a corrugated surface 2222, and the water spraying module further includes a throttling tube 333, and the throttling tube 333, the water inlet valve 32 and the water sprayer 31 are connected in sequence.

[0252] Specifically, during use, the water inlet valve 32 controls the water supply. When the water is supplied, the water flows through the throttling tube 33 to control the total flow rate in the tube within a certain range (for example, 300±50mL under the water pressure of domestic water), and then the water flow is distributed to the wet membrane assembly 22 below through the water spray hole 301 as needed. The water flows downward in the concave structure 223 through the first water inlet hole 224 and the second water inlet hole 225.

[0253] The water flowing down from the first water inlet hole 224 is evenly distributed through the corrugated surface 2222, so as to evenly infiltrate and flush the humidifying membrane, thereby achieving better water supply uniformity and preventing the life of the humidifying membrane from being shortened due to excessive flushing water. Since the first water inlet hole 224 is arranged in the middle, the protrusions and grooves formed on the corrugated surface 2222 extend along the length direction of the wet membrane 222, so that the water can be evenly distributed.

[0254] More importantly, since the ceiling-mounted central humidification equipment is installed by ceiling suspension, it will tilt forward and backward during the installation process. By configuring the corrugated surface 2222, the uneven water flow distribution caused by installation errors can be better solved. The corrugated surface 2222 is used to guide the water flow so that the water can be evenly distributed along the length direction of the wet film 222.

[0255] In addition, the diverted water will also be stored in the water tank 21 for humidification, thereby achieving the effect of limiting the amount of water supplied to the wet membrane 222 while ensuring the water replenishment speed of the water tank 21.

[0256] The entity of the throttling tube 33 may adopt a water pipe structure with a throttling function in conventional technology, which will not be limited or elaborated herein.

[0257] By adding a throttling tube in the water sprinkling module and using the throttling tube to throttle the input water flow, the rapid change of water flow caused by water pressure fluctuation can be effectively reduced during the water supply process. At the same time, the water can be better evenly distributed and supplied by coordinating the flow diversion of the sprinkling hole and the first water inlet hole. In addition, by forming a corrugated surface on the top surface of the wet membrane and using the corrugated surface to guide the water flow direction, the wet membrane can be evenly wetted and flushed, and the life of the wet membrane can be avoided from being shortened due to excessive flushing water while achieving better water supply uniformity. The water supply flow of the ceiling-mounted central humidification equipment can be conveniently controlled and the wet membrane wetting uniformity can be improved to improve the humidification effect.

[0258] In order to meet the requirements of automatic control, a controller (such as a single chip microcomputer, etc.) is integrated in the electric control board. The specific control method is that when the ceiling-mounted central humidification device starts the humidification function, the controller is configured so that the first water level detector 26 detects that the water level value is less than the first water level value and triggers the water inlet valve 32 to open, and the controller is also configured so that the first water level detector 26 detects that the water level value is greater than the second water level value and triggers the water inlet valve 32 to close.

[0259] Specifically, when the ceiling-mounted central humidifier performs humidification mode, the water supply is controlled according to the water level in the water tank 21. The first water level detector 26 sends a water level value signal to the controller, and the controller controls the water inlet valve 32 to open or close the water supply, so that the wet film 222 can be well and evenly wetted on the one hand, and too much water in the water tank 21 is avoided on the other hand.

[0260] In another embodiment, during use, there is a situation where an electrical component fails, resulting in a situation where water cannot flow in or cannot be turned off.

[0261] To this end, the control method also includes: the controller is further configured to issue a water supply abnormality alarm when the first water level detector 26 detects that the water level value is continuously less than the first water level value and the duration exceeds a first time value.

[0262] Specifically, in the humidification mode, after the controller controls the water inlet valve 32 to open the water supply, if the first water level detector 26 detects that the water level value is continuously less than the first water level value, it means that no water is supplied to the humidification module 2. At this time, a water supply abnormality alarm is issued. The alarm method can adopt conventional alarm methods such as sound, light and electricity, which are not limited or elaborated here.

[0263] In another embodiment, the controller is further configured to start the drainage pump when the first water level detector 26 detects that the water level value is continuously greater than the second water level value and the duration exceeds a second time value.

[0264] Specifically, in the humidification mode, after the controller controls the water inlet valve 32 to open the water supply, if the water level exceeds the second water level value of the water tank 21, the water inlet valve 32 should be closed. When the water inlet valve 32 fails, because the water level in the water tank 21 continues to exceed the second water level value and the duration exceeds the second time value, the drainage pump is started to drain water. In this case, the water supply abnormality alarm can also be started.

[0265] Furthermore, the controller is also configured to, after starting the drainage pump, issue a water supply abnormality alarm when the first water level detector 26 detects that the water level value is continuously greater than the second water level value and the duration exceeds a third time value.

[0266] Specifically, in the humidification mode, when the drainage pump is started to drain water, if the second water level value is reached and the duration exceeds the third time value, it means that the drainage pump fails, and a water supply abnormality alarm needs to be issued in time.

[0267] In another embodiment, when the ceiling-mounted central humidification device turns off the humidification function, since there is still a certain amount of water in the water tank 21, in order to prevent the wet film 222 from being soaked in water for a long time and becoming moldy, the water in the water tank 21 needs to be drained out in time.

[0268] To this end, the control method also includes the controller being configured to start the drain pump to drain the water in the water tank into the water receiving tray and start the electric heating component to dry the wet film after the first water level detector detects that the water level value is continuously lower than the first water level value and the duration exceeds a fourth time value.

[0269] Specifically, after the ceiling-mounted central humidification device turns off the humidification function, the controller will start the drainage pump to drain the water in the water tank 21 into the water receiving tray 6 below. The water level in the water tank 21 will drop below the first water level value, and after the first water level detector detects that the water level value is continuously lower than the first water level value and the duration exceeds the fourth time value, it indicates that the water in the water tank 21 has been completely drained. At this time, the electric heating component 72 can be started to dry the wet film 222.

[0270] At the same time, after the first water level detector detects that the water level value is continuously lower than the first water level value and the duration exceeds the fourth time length, the controller will simultaneously turn off the drainage pump 23 .

[0271] In some embodiments, the first water level detector 26 includes a lower liquid level switch 261 and an upper liquid level switch 262 , wherein the height of the lower liquid level switch is lower than that of the upper liquid level switch, and the lower liquid level switch and the upper liquid level switch are electrically connected to the controller respectively.

[0272] Specifically, in order to accurately detect the water level in the water tank 21, two liquid level switches arranged up and down are used to detect the water level. The lower liquid level switch 261 is used to match the first water level value during the detection process, and the upper liquid level switch 262 is used to match the second water level value during the detection process.

[0273] In some embodiments, in order to facilitate unified assembly, a support rod (not shown) is provided in the water tank, and the lower liquid level switch and the upper liquid level switch are both provided on the support rod.

[0274] Specifically, during the assembly process, the lower liquid level switch and the upper liquid level switch are both installed on the support rod, and then a float is also provided on the support rod. The float floats according to the liquid level in the water tank 21 and triggers the lower liquid level switch and the upper liquid level switch to conduct. When the water level in the water tank 21 is low, the float will drop to the position of the lower liquid level switch, and then the float will trigger the lower liquid level switch to conduct, the lower liquid level switch will turn on the ON working state, and the water supply waterway will start to supply water. When the water level inside the water tank rises, the float rises to the upper liquid level switch position accordingly, and the float will trigger the upper liquid level switch to conduct, the upper liquid level switch will turn on the ON working state, and the water supply waterway will stop supplying water.

[0275] By utilizing the integrated high and low position floats, the water volume requirement inside the water tank is met. When the humidification system stops humidifying, the water pump in the water tank will start draining and discharge the excess water inside the water tank into the water receiving tray.

[0276] In another embodiment, in order to keep the water in the water tank 21 clean during use to improve the humidification effect. In the humidification mode, when the device runs continuously for a set operating time, the device will perform a flushing and water replacement operation, specifically: the controller is configured to trigger the drain pump to drain all the water in the water tank 21 after the device runs continuously for a set operating time, and during the drainage process, since the water level in the water tank 21 is lower than the first water level value, it automatically triggers the opening of the water inlet valve 32 to continuously spray and clean the water film 222. After executing the above operation process for the set maintenance time, the controller turns off the drain pump and relies on the first water level detector to control the water level in the water tank 21 between the first water level value and the second water level value, so that the water film 222 continues to humidify.

[0277] By completely and effectively replacing the water in the water tank 21 and cooperating with the water spraying module to spray and clean the wet film, the problem of the water quality in the water tank 21 deteriorating after the equipment has been running continuously for a long time, resulting in a reduced humidification effect, can be solved. After performing the above operations, the water tank 21 can be replaced with new water, and the wet film 222 can be cleaned to obtain a good humidification effect. In one embodiment, a second water level detector 61 is provided in the water receiving tray, and the second water level detector is electrically connected to the controller, and the controller is configured to trigger the drainage pump to stop working and issue an overflow alarm when the second water level detector detects that the water level value is continuously greater than the third water level value and the duration exceeds the fifth time value.

[0278] Specifically, the second water level detector 61 is disposed in the water receiving tray 6 to detect the water level in the water receiving tray 6. When the drain pipe drains smoothly, the water discharged from the drain pump 23 into the water receiving tray 6 is automatically discharged to the outside through the drain pipe 62.

[0279] When the drain pipe 62 is blocked and the drainage is not smooth, the water level in the water receiving tray 6 will gradually rise. When the second water level detector 61 detects that the water level is higher than the third water level value and lasts for more than the fifth time value, it means that the drain pipe 62 of the water receiving tray 6 is blocked, so that the water receiving tray 6 cannot drain, or the upper liquid level switch 262 in the water tank 21 fails, causing the water channel to continue to supply water and overflow from the water tank 21. At this time, the drainage pump 23 is triggered to stop working and an overflow alarm is issued.

[0280] In one embodiment, the second water level detector 61 may be an overflow float, which is installed in the water receiving tray 6. The working principle of the overflow float is that when the drainage pump 23 in the water tank 21 drains water into the water receiving tray 6, the overflow float is triggered by the buoyancy of the water in the water receiving tray 6, and the controller stops the drainage pump 23 in the water tank 21 from draining water, thereby protecting the humidification system from the risk of overflow.

[0281] By utilizing the combination of high and low position floats and overflow floats, the system can not only control the water volume and water level according to the humidification requirements, but also realize the drainage overflow risk alarm, which is highly practical and safe.

[0282] In another embodiment, a wind pressure switch 46, a first temperature sensor 47, a second temperature sensor 40 and a humidity sensor 48 are provided in the casing; the wind pressure switch, the first temperature sensor and the humidity sensor are arranged at the air inlet and are electrically connected to the controller respectively; the second temperature sensor is arranged at the air outlet and is electrically connected to the controller.

[0283] Specifically, after the ceiling-mounted central humidification device starts the humidification function, the controller will detect relevant startup parameters based on the wind pressure switch 46, the first temperature sensor 47 and the humidity sensor 48 to determine whether the startup conditions are met, and then start the water inlet valve 32 to open for humidification operation.

[0284] Among them, the control method also includes that when the humidification function of the ceiling-mounted central humidification equipment is started, the controller is configured to start the electric heating component when conditions one, two and three are met; wherein, condition one is that the wind pressure detected by the wind pressure switch is greater than the set wind pressure; condition two is that the temperature value detected by the first temperature sensor is lower than the set temperature value; condition three is that the humidity value detected by the humidity sensor is lower than the set humidity value.

[0285] Specifically, when the humidifier starts to humidify, the system detects whether the wind pressure switch meets the set condition one to prevent the electric heating component 72 from drying out when the air volume is low or there is no air volume, thereby ensuring the reliability of the electric heating; when condition one is met, the first temperature sensor detects whether the inlet dry-bulb temperature meets the set condition two. When the inlet temperature is too high, in order to protect the electric heating component 72 and the surrounding plastic parts from being too high and affecting the product reliability, it is prohibited to turn on the electric heating component 72; when condition two is met, the humidity sensor 48 detects whether the inlet wet-bulb temperature meets the set condition three. At higher humidity, the electric heating component 72 is turned on to increase the humidification amount. When high-temperature and high-humidity air passes through the normal-temperature air duct, condensation may occur, affecting the product reliability. Therefore, it is prohibited to turn on the electric heating component 72.

[0286] When condition three is met, the controller is further configured to control the heating power of the electric heating component according to the temperature value detected by the second temperature sensor. The system detects the outlet air temperature, and according to the difference between the outlet air temperature and the inlet air temperature, turns on the electric heating component 72 in different gears to ensure that the outlet air temperature is within the comfortable temperature range for human body. If the above conditions are not met, the system will return to the initial condition and re-test until the conditions are met.

[0287] In another embodiment, since a certain amount of water is stored in the water tank 21 during use, when operating in a low-temperature environment, the outdoor ambient temperature is judged by detecting the temperature value detected by the first temperature sensor, and when the temperature value detected by the first temperature sensor is lower than the antifreeze temperature value, the controller will trigger the drain pump to start and close the water inlet valve to drain the water in the water tank 21, thereby avoiding the water in the water tank 21 from thawing and causing damage to the wet film, so that the equipment has a stronger antifreeze ability and improves the reliability of use.
