[0002] Toilets or bathrooms are usually relatively closed and poorly ventilated spaces. They are humid, have poor air quality, and are prone to odor, so the air inside needs to be treated.

[0003] The rotary dehumidifier is an efficient and environmentally friendly dehumidification device, which is mainly composed of a rotor, a drive motor and a regeneration heater. When the rotary dehumidifier is working, the rotor will rotate at a certain speed, sucking in the indoor humid air and adsorbing it on the rotor to reduce the air humidity. When the moisture adsorbed by the rotor reaches a certain amount, the regeneration heater will heat the rotor to evaporate the moisture attached to the rotor, so that the rotor returns to a dry state to perform adsorption dehumidification again.

[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0039] In the air dehumidification device of the utility model, the dehumidification component 2 does not need to work at full power during the overall dehumidification process, thereby achieving energy consumption in the overall dehumidification process while ensuring the dehumidification efficiency of the dehumidification component 2, thereby achieving energy saving and power saving.

[0040] In one embodiment of the present invention, Figures 1 to 5 As shown, the air dehumidification device includes a shell 1, a dehumidification component 2 and a condensation component 3. The wall surface of the shell 1 is provided with an air inlet 11 and an air outlet 12, and an installation cavity 13 is formed inside the shell 1. The air inlet 11 and the air outlet 12 are both connected to the installation cavity 13. The dehumidification component 2 and the condensation component 3 are both installed in the installation cavity 13. The dehumidification component 2 is used to adsorb water vapor in the indoor air and heat the adsorbed water vapor into water vapor. The dehumidification component 2 is provided with a water vapor outlet 215, and the condensation component 3 is provided with a condensation inlet 311. The water vapor outlet 215 is connected to the condensation inlet 311. One of the water vapor outlet 215 and the condensation inlet 311 is provided with a first humidity detection component 41. The first humidity detection component 41 is electrically connected to the dehumidification component 2, and the first humidity detection component 41 is used to detect the relative humidity of the water vapor discharged by the dehumidification component 2.

[0041] According to the air dehumidification device provided by the utility model, when the air dehumidification device starts to operate, the dehumidification component 2 sucks indoor air from the air inlet 11 into the installation cavity 13, so that the dehumidification component 2 adsorbs water vapor in the indoor air, separates the water vapor from the indoor air, and realizes dehumidification of the indoor air; at the same time, the dehumidification component 2 heats the adsorbed water vapor into water vapor, and transports the water vapor to the condensation component 3 through the water vapor outlet 215 and the condensation inlet 311 for condensation, so as to discharge the water vapor from the dehumidification component 2, so that the dehumidification component 2 can continue to dehumidify the indoor air.

[0042] Since one of the water vapor outlet 215 and the condensation inlet 311 is provided with the first humidity detection element 41 to detect the relative humidity of the water vapor discharged from the dehumidification component 2, the operation power of the dehumidification component 2 can be changed according to the water vapor relative humidity detection data of the first humidity detection element 41. When it is detected that the relative humidity of the water vapor discharged from the dehumidification component 2 is relatively high, the operation power of the dehumidification component 2 can be increased to improve the dehumidification efficiency of the dehumidification component 2; when it is detected that the relative humidity of the water vapor discharged from the dehumidification component 2 is relatively low, the operation power of the dehumidification component 2 can be reduced to reduce the operation energy consumption of the dehumidification component 2.

[0043] Therefore, the air dehumidification device provided in this embodiment can be provided with a first humidity detection element 41 at one of the water vapor outlet 215 and the condensation inlet 311 to detect the real-time relative humidity of the water vapor discharged by the dehumidification component 2, thereby changing the operating power of the dehumidification component 2 in real time, so that the dehumidification component 2 does not need to maintain full power operation during the overall dehumidification process, thereby achieving energy saving and power saving while ensuring the dehumidification efficiency of the dehumidification component 2.

[0044] The first humidity detection component 41 is preferably a humidity sensor, and the detection probe of the humidity sensor is located at the water vapor outlet 215 or the condensation inlet 311 .

[0045] It should be noted here that the humidity detection component can control the operating power of electrical equipment such as the dehumidification component 2 through a connecting circuit. The connecting circuit between the humidity detection component and the electrical equipment is a prior art and will not be described in detail here.

[0046] In this embodiment, if Figure 2 and Figure 3 As shown, the dehumidification component 2 includes a dehumidification wheel assembly 21 and a centrifugal fan 22. The dehumidification wheel assembly 21 is detachably connected to the inner wall surface of the housing 1, the water vapor outlet 215 is provided at the dehumidification wheel assembly 21, and the first temperature detection member is installed at the water vapor outlet 215. The centrifugal fan 22 is connected to the dehumidification wheel assembly 21, and the centrifugal fan 22 is located on the side of the dehumidification wheel assembly 21 away from the air inlet 11, and the impeller of the centrifugal fan 22 faces the air inlet 11.

[0047] It is understandable that when the air dehumidification device is running, the indoor air is sucked into the dehumidification wheel assembly 21 through the centrifugal fan 22, and the dehumidification wheel assembly 21 absorbs water vapor in the air and heats the absorbed water vapor into high-temperature and high-humidity water vapor. By installing the first humidity detection component 41 at the water vapor outlet 215, the first humidity detection component 41 can directly detect the humidity of the water vapor after the dehumidification wheel assembly 21 is heated, ensuring that the humidity detected by the first humidity detection component 41 can accurately reflect the amount of water vapor absorbed by the dehumidification wheel assembly 21, and further ensuring that the detection data of the first humidity detection component 41 can accurately reflect the dehumidification efficiency of the dehumidification wheel assembly 21, so as to improve the control effect of the operating power of the dehumidification wheel assembly 21.

[0048] Specifically, Figures 2 to 4 As shown, the dehumidification wheel assembly 21 includes a mounting frame 211, a rotor body 212, an adsorbent 213 and a heating element 214. The mounting frame 211 is threadedly connected to the inner wall surface of the housing 1, the rotor body 212 is rotatably arranged on the mounting frame 211, the adsorbent 213 is connected to the blades of the rotor body 212, and the adsorbent 213 rotates integrally with the rotor body 212. Specifically, the adsorbent 213 is preferably a ceramic disk, so that the adsorbent 213 is driven to rotate through the rotor body 212, thereby increasing the contact area between the adsorbent 213 and the indoor air, thereby increasing the adsorption efficiency of the adsorbent 213 on water vapor in the indoor air. The heating element 214 is arranged on the side of the mounting frame 211 facing the condensation component 3, the adsorbent 213 is rotatably arranged through the heating element 214, and the heating element 214 is provided with a water vapor outlet 215.

[0049] It can be understood that after the indoor air is sucked into the installation cavity 13 through the centrifugal fan 22, the wheel body 212 absorbs water vapor in the air through the adsorption element 213. After running for a certain period of time, the wheel body 212 rotates to rotate the adsorption element 213 adsorbed with water vapor to the heating element 214, so that the heating element 214 can be used to heat the water vapor adsorbed by the adsorption element 213, and the water vapor is heated to high-temperature and high-humidity water vapor. The water vapor is discharged from the water vapor outlet 215, so that the first humidity detection element 41 at the water vapor outlet 215 can obtain the real-time humidity condition of the water vapor, thereby controlling the rotation power of the wheel body 212.

[0050] The heating element 214 is preferably a heating plate, into which processed high-temperature gas is introduced to exchange heat with the water vapor adsorbed by the adsorbent 213, thereby heating the water vapor adsorbed by the adsorbent 213 into high-temperature and high-humidity water vapor.

[0051] It should be noted that the wall surface of the mounting frame 211 facing the inner wall surface of the housing 1 is formed with a threaded countersunk hole, and the housing 1 is provided with a mounting hole. The mounting frame 211 is fixed to the inside of the housing 1 by screws or bolts, so that the rotor body 212, the adsorbent 213 and the heating element 214 are fixed on the mounting frame 211. The mounting frame 211 is formed with a mounting boss on the side facing the centrifugal fan 22, and a threaded hole is provided in the mounting boss. The fixing frame of the centrifugal fan 22 is provided with a mounting hole, and the centrifugal fan 22 can be locked to the mounting frame 211 by screws or bolts to achieve the fixation of the centrifugal fan 22.

[0052] Furthermore, if Figure 2 and Figure 3 As shown, the air dehumidification device also includes a power drive board 23. The rotor body 212, the heating element 214 and the centrifugal fan 22 are all electrically connected to the power drive board 23, and the first humidity detection element 41 is electrically connected and / or signal connected to the power drive board 23. Then the power drive board 23 can obtain the relative humidity of water vapor at the water vapor outlet 215 through the first humidity detection element 41, thereby obtaining the dehumidification efficiency of the rotor body 212, the adsorbent 213 and the heating element 214. When the relative humidity of water vapor at the water vapor outlet 215 is large, the power drive board 23 increases the operating power of the rotor body 212 and the heating element 214 to accelerate the operation of the rotor body 212 and speed up the rate at which the heating element 214 converts water vapor into water vapor; and when the relative humidity of water vapor at the water vapor outlet 215 of the heating element 214 is small, the power drive board 23 reduces the operating power of the rotor body 212 and the heating element 214 to decelerate the operation of the rotor body 212, thereby reducing energy consumption.

[0053] It should be noted that the mounting frame 211 is connected to a stepper motor 217, the rotating shaft of the stepper motor 217 is connected to the rotating wheel body 212, and the power driving board 23 is electrically connected to the stepper motor 217, so that the power driving board 23 controls the rotating speed of the rotating wheel body 212. At the same time, the mounting frame 211 is connected to a shaded pole motor 218, the shaded pole motor 218 is connected to the heating element 214, and the power driving board 23 is electrically connected to the shaded pole motor 218, so that the power driving board 23 controls the heating efficiency of the heating element 214 for adsorbing water vapor.

[0054] In this embodiment, if Figure 2 , Figure 3 and Figure 5 As shown, the condensation component 3 includes a condensation bracket 31 and a condensation tube 32. The condensation bracket 31 is detachably connected to the dehumidification wheel assembly 21, and the condensation inlet 311 is arranged on the side of the condensation bracket 31 facing the dehumidification wheel assembly 21. The condensation tube 32 is installed on the condensation bracket 31, and the water vapor inlet of the condensation tube 32 is connected to the condensation inlet 311, and the water vapor outlet 313 of the condensation tube 32 is connected to the water vapor inlet 216 of the dehumidification wheel assembly 21.

[0055] It can be understood that after the high-temperature and high-humidity water vapor is input into the condenser 32 through the condensation inlet 311, part of the high-temperature and high-humidity water vapor is condensed to form liquid water, and the remaining water vapor is converted into medium-temperature and high-humidity water vapor, and re-enters the dehumidification wheel assembly 21 from the water vapor outlet 313 of the condenser 32, and after being re-heated by the heating element 214 in the dehumidification wheel assembly 21, it enters the condenser 32 again for condensation, thereby ensuring that the water vapor adsorbed by the dehumidification wheel assembly 21 is completely condensed into liquid water to ensure the dehumidification effect.

[0056] It should be noted here that the condensing bracket 31 is formed with a threaded hole, and a boss is formed on the side of the mounting frame 211 facing the condensing bracket 31. The boss is provided with a through hole, and bolts or screws pass through the through hole and the threaded hole to install the condensing bracket 31 in the mounting frame 211 to achieve connection between the condensing component 3 and the dehumidification wheel assembly 21.

[0057] Furthermore, if Figure 5 As shown, a drainage outlet 312 is formed at the bottom of the condensation bracket 31 , and the drainage outlet 312 is connected to the water outlet of the condensation pipe 32 to discharge the condensed liquid water from the condensation pipe 32 through the drainage outlet 312 .

[0058] It should be noted that the drainage outlet 312 can be directly connected to a drainage structure such as a floor drain in the room to drain the condensed liquid water to the drainage structure such as a floor drain. In addition, a water receiving tray can be provided below the drainage outlet 312, and a drainage pump is provided at the bottom of the water receiving tray, and the drainage pump is connected to a drainage structure such as a floor drain in the room. A water level sensor is provided in the water receiving tray to detect the water level in the water receiving tray. When the water level sensor detects that the water receiving tray is full of water, the drainage pump is controlled to work to drain the liquid water in the water receiving tray to a drainage structure such as a floor drain.

[0059] In this embodiment, Figures 1 to 3 As shown, the shell 1 includes an upper shell 14 and a bottom shell 15, and the upper shell 14 and the bottom shell 15 are detachably connected. The upper shell 14 forms a first opening, and the bottom shell 15 forms a second opening. The first opening and the second opening are arranged to form an installation cavity 13 to wrap the dehumidification component 2 and the condensation component 3 in the installation cavity 13 in the upper shell 14 and the bottom shell 15 to provide a certain degree of protection for the dehumidification component 2 and the condensation component 3.

[0060] Specifically, a mounting boss is formed at the top of the upper shell 14, a threaded hole is provided in the mounting boss, a threaded hole is formed at the top of the bottom shell 15, bolts or studs pass through the threaded hole at the top of the bottom shell 15 and the mounting boss at the top of the upper shell 14 to threadably connect the top of the bottom shell 15 and the top of the upper shell 14; at the same time, a threaded hole is formed at the bottom of the upper shell 14, a mounting boss with a threaded hole is formed at the bottom of the bottom shell 15, bolts or studs pass through the mounting boss at the bottom of the bottom shell 15 and the threaded hole at the bottom of the upper shell 14 to threadably connect the bottom of the bottom shell 15 and the bottom of the upper shell 14, thereby realizing a detachable connection between the upper shell 14 and the bottom shell 15, so as to facilitate the installation, disassembly and maintenance of the upper shell 14 and the bottom shell 15.

[0061] Among them, Figure 1 and Figure 2 As shown, the air inlet 11 is provided with a second humidity detection member 42, and the second humidity detection member 42 is used to detect the relative humidity of the air sucked into the installation cavity 13. The relative humidity of the air input into the air dehumidification device can be detected by the second humidity detection member 42, and the initial working power of the dehumidification component 2 and the condensation component 3 can be determined to ensure the initial efficiency of the air dehumidification device when it starts to operate.

[0062] Meanwhile, during the operation of the air dehumidification device, the operating power of the dehumidification component 2 can be controlled by comparing the relative humidity of the first humidity detection element 41 and the relative humidity difference of the second humidity detection element 42 to further increase the dehumidification efficiency.

[0063] For example, when the relative humidity detected by the first humidity detection component 41 is greater than or equal to the relative humidity detected by the second humidity detection component 42, it means that the indoor air humidity is still relatively high, and part of the water vapor at the condenser 32 flows back to the heating component 214 for heating. At this time, the operating power of the wheel body 212 and the heating component 214 can be increased through the power drive board 23 to increase the initial efficiency of the air dehumidification device.

[0064] When the relative humidity detected by the first humidity detection component 41 is lower than the relative humidity detected by the second humidity detection component 42, it means that the indoor air humidity has decreased and there is no reflux water vapor in the heating component 214. At this time, the power drive board 23 can be used to reduce the operating power of the wheel body 212 and the heating component 214 to reduce the energy consumption of the wheel body 212 and the heating component 214, thereby achieving energy saving and consumption reduction.

[0065] Preferably, the second humidity detecting member 42 is a humidity sensor.

[0066] Combine the following Figures 1 to 5 The specific working process of a specific embodiment of the air dehumidification device is described.

[0067] After the air dehumidification device is started up, the relative humidity of the air input into the air dehumidification device is detected by the second humidity detection component 42 to determine the initial working power of the wheel body 212 and the heating component 214. The power drive board 23 drives the wheel body 212 and the heating component 214 to operate according to the initial working power, so as to utilize the adsorption component 213 on the wheel body 212 to adsorb water vapor in the air.

[0068] The adsorption element 213 is then rotated to the heating element 214 to convert the adsorbed water vapor into water vapor. At this time, the high-temperature and high-humidity water vapor is discharged from the water vapor outlet 215 of the heating element 214 and input into the condenser 32 for condensation. Part of the water vapor forms liquid water droplets and is discharged from the drain port of the condenser 32. The remaining water vapor is adsorbed by the wheel body 212 and heated by the heating element 214 again, and then input into the condenser 32 for condensation, forming a dehumidification cycle of the air dehumidification device.

[0069] During the dehumidification cycle, the second humidity detection member 42 at the air inlet 11 detects the humidity of the air sucked into the installation cavity 13, and the first humidity detection member 41 at the water vapor outlet 215 of the heating member 214 detects the humidity of the water vapor discharged by the heating member 214. When the relative humidity detected by the first humidity detection member 41 is greater than or equal to the relative humidity detected by the second humidity detection member 42, the operating power of the rotor body 212 and the heating member 214 is increased through the power drive board 23 to increase the initial efficiency of the air dehumidification device. When the relative humidity detected by the first humidity detection member 41 is less than the relative humidity detected by the second humidity detection member 42, the operating power of the rotor body 212 and the heating member 214 is reduced through the power drive board 23 to reduce the energy consumption of the rotor body 212 and the heating member 214, thereby achieving energy saving and consumption reduction.

[0070] The utility model also provides a bathroom cabinet 5, such as Figure 6 and Figure 7 As shown, the bathroom cabinet 5 includes a cabinet body and the air dehumidification device described in any one of the above embodiments. The cabinet body is formed with a mounting portion, and the air dehumidification device is mounted on the mounting portion.

[0071] An air inlet grille 51 and an air outlet grille 52 are formed on the outer wall surface of the cabinet body. The air inlet grille 51 is connected to the air inlet 11 , and the air outlet grille 52 is connected to the air outlet 12 .

[0072] The bathroom cabinet 5 provided in this embodiment has all the beneficial effects of the above-mentioned air dehumidification device, which will not be described in detail here. In addition, by integrating the air dehumidification device into the cabinet body, the dehumidification device can be installed in a small bathroom without occupying the space in the bathroom, ensuring that the bathroom space is neat and beautiful, and the bathroom cabinet 5 has the function of indoor dehumidification, providing users with a comfortable space experience.

[0073] It should be noted here that the arrangement of the air inlet 11 and the air outlet 12 on the housing 1 can form a variety of arrangements, such as a forward-front-out arrangement in which the air inlet 11 and the air outlet 12 are both facing the front of the cabinet body; or a rear-in-rear-out arrangement in which the air inlet 11 and the air outlet 12 are both away from the front of the cabinet body; or a forward-back-out arrangement in which the air inlet 11 faces the front of the cabinet body and the air outlet 12 faces away from the front of the cabinet body; or a rear-in-front-out arrangement in which the air inlet 11 faces away from the front of the cabinet body and the air outlet 12 faces the front of the cabinet body; or a rear-in-front-out arrangement in which the air inlet 11 faces away from the front of the cabinet body and the air outlet 12 faces the front of the cabinet body; or a forward-down-out arrangement in which the air inlet 11 faces the front of the cabinet body and the air outlet 12 faces the bottom of the cabinet body; or a bottom-in-front-out arrangement in which the air inlet 11 faces the bottom of the cabinet body and the air outlet 12 faces the front of the cabinet body. The positions of the air inlet 11 and the air outlet 12 can be set according to actual needs.

[0074] Specifically, when it is necessary to clean and maintain the air dehumidification device integrated in the cabinet body, the air dehumidification device can be installed on the cabinet body in the following exemplary installation manner:

[0075] In the first installation mode, when the cabinet body is a bathroom cabinet 5 with a swing door, a mounting groove 53 is formed on the cabinet body, and the bottom surface of the housing 1 is slidably connected to the mounting groove 53 via a guide rail 54. When the air dehumidifier needs to be pulled out, the air dehumidifier can be pulled out of the mounting groove 53 along the extension direction of the guide rail 54; and when the air dehumidifier needs to be pushed in, the air dehumidifier can be pushed into the mounting groove 53 along the extension direction of the guide rail 54, so as to facilitate cleaning and maintenance of the air dehumidifier.

[0076] It should be noted that the side wall of the mounting groove 53 is rotatably connected to the cabinet panel 55 of the cabinet body, and the air inlet grille 51 and the air outlet grille 52 are mounted on the cabinet panel 55, so that the air dehumidifier can dehumidify the air in the bathroom through the air inlet grille 51 and the air outlet grille 52 while ensuring the appearance of the cabinet body. When the air dehumidifier needs to be pulled out, it only needs to open the cabinet panel 55, which is convenient and quick.

[0077] In the second installation mode, when the cabinet body is a bathroom cabinet with a drawer door 5, the cabinet body is formed with a drawer assembly, and the housing 1 is installed in the drawer assembly. Then, the air dehumidifier can be pulled out or pushed in by pulling out or pushing in the drawer assembly, which is convenient for cleaning and maintenance of the air dehumidifier.
