Description

Technical Field

[0001] This invention relates to a humidifier, and more particularly to a humidifier for use in dehumidifier cabinets. Background Technology

[0002] A dehumidifying cabinet is a storage cabinet that uses dehumidification technology to reduce the humidity inside, thereby achieving the purposes of preventing moisture, mold, oxidation, rust, and trace moisture absorption. It is generally used for storing books and paintings, tea, electronic products, etc. We all know that moisture prevention means preventing excessive humidity in the air, as excessive humidity allows mold to multiply rapidly, causing items to mold and spoil. However, users have found that excessively dry air inside the dehumidifying cabinet can also cause problems. For example, oil paintings and cameras, if exposed to an overly dry environment for a long time, are prone to cracking or peeling of the paint, while cameras may experience problems such as cracked focus rings. Especially when the external humidity of the dehumidifying cabinet is already very dry, users cannot increase the internal humidity by simply stopping the dehumidification module. Common solutions include: 1. Placing a cup of hot water inside the cabinet; 2. Installing a humidifier inside the cabinet.

[0003] While placing a cup of hot water inside the dehumidifier can effectively alleviate its dryness, it creates new problems. For example, the temperature inside the dehumidifier rises significantly, and the humidifying effect weakens as the hot water cools, requiring frequent refills, which is inconvenient. Furthermore, placing a cup of hot water inside the dehumidifier is inherently dangerous; spillage could damage the items inside, with potentially serious consequences.

[0004] Regarding the second method mentioned above, a humidifier is installed inside the dehumidifying cabinet. For example, Chinese patent document CN206390666U discloses a constant temperature and moisture-proof cultural relic display cabinet, which relates to the field of visual display. The display cabinet includes a support platform and a display frame. The display frame is fixed to the top of the support platform. A temperature sensor and a humidity sensor are installed inside the display frame. The display cabinet also includes a temperature and humidity controller. The temperature sensor and humidity sensor are electrically connected to the temperature and humidity controller. A humidifier and a heater are installed inside the support platform. The humidifier and heater are electrically connected to the temperature and humidity controller. The steam outlet of the humidifier is located inside the display frame. The display frame has a double-layer structure: a protective outer shell and an exchange inner shell. A certain installation space is left between the protective outer shell and the exchange inner shell. Several heating elements are distributed in the installation space. The heating elements are connected to the heater, thereby controlling the temperature and humidity in the display cabinet and ensuring the stability of the temperature and humidity inside the display frame. The aforementioned patent documents do not disclose the type of humidifier used. Humidifiers known to those skilled in the art include ultrasonic humidifiers, pure humidifiers, electrically heated humidifiers, immersion electrode humidifiers, and cold mist humidifiers. The following analysis examines the effectiveness of various humidifiers in dehumidifier cabinets:

[0005] 1. Ultrasonic humidifiers generally use high-frequency ultrasonic oscillation at 1.7MHz, which can atomize water into ultra-fine particles of 1-5 microns, resulting in high humidification intensity and efficiency. However, because ultrasonic humidifiers humidify too quickly, they can easily form mist droplets on the surface of items inside cabinets near the humidifier, causing excessive humidity on the surface of the items and potentially damaging them.

[0006] 2. Pure humidifiers use molecular sieve evaporation technology to remove calcium and magnesium ions from the water and wash the air with a water curtain. While humidifying, they can also filter and purify germs, dust and particulate matter in the air. The humidified and clean air is then delivered to the room by a fan, thereby improving the humidity and cleanliness of the environment. This type of humidifier is bulky and expensive, and is not suitable for use in dehumidifying cabinets.

[0007] 3. Electric heating humidifiers heat water to 100°C in a heating element to produce steam, which is then blown out by a fan. This type of humidifier can cause the problems described in Method 1 above.

[0008] 4. Immersion electrode humidifiers use large-area electrodes immersed in water as terminals and water as the heating medium. When current transfers electrical energy through water, heat is generated, causing the water to boil and produce steam. This type of humidifier is relatively large and will also produce the problems described in Method 1 above.

[0009] 5. Cold mist humidifiers increase relative humidity by using a fan to force air through a water-absorbing medium, allowing it to come into contact with and exchange with water. The advantage of this type of humidifier is its automatic adjustment based on relative humidity; it humidifies more when relative humidity is low and less when relative humidity is high. However, its disadvantages include low humidification output, long humidification time, and uncontrolled evaporation even when humidification is not needed.

[0010] In conclusion, from the perspective of protecting the items inside a dehumidifying cabinet, a cold mist humidifier is undoubtedly the most suitable humidifier for such applications. However, the low humidification capacity and long humidification time of cold mist humidifiers will be a bottleneck in their use in dehumidifying cabinets, and there is currently no technology to overcome this bottleneck. Furthermore, since a dehumidifying cabinet is a relatively enclosed space, users rarely observe the environment inside. If the humidifier tipes over, how can water leakage be prevented? There is no corresponding solution in existing technology. Therefore, the technical problems that need to be solved now are how to increase the humidification capacity of cold mist humidifiers, shorten the humidification time, and prevent water leakage when the humidifier is tipped over or tilted, thereby meeting the requirements for humidifier use in dehumidifying cabinets. Summary of the Invention

[0011] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a moisture-proof cabinet humidifier with a large humidification capacity, moderate humidification time, good humidification effect and high safety performance.

[0012] The technical solution adopted in this invention is as follows: This invention includes a water tank with a water inlet and a sealing plug. The top of the water tank has a through hole. The humidifier also includes an absorbent cotton core, the bottom of which passes through the through hole and enters the water tank, while the top of the absorbent cotton core protrudes from the through hole. Furthermore, the humidifier also includes an absorbent layer, which is laid flat above the water tank. The absorbent layer has holes for mounting the absorbent cotton core, and the top of the absorbent cotton core protrudes from the through hole. The absorbent cotton core is inserted into the bottom of the mounting hole and exits from the top of the mounting hole. The inner wall of the mounting hole fits tightly with the outer wall of the absorbent cotton core. The top of the water tank is also provided with a shell, on which a fan is installed. The fan is located above the absorbent layer, and the top of the shell is provided with an air inlet adapted to the fan. The side of the shell is provided with several air outlets. The fan draws in air from outside the shell through the air inlet and blows it toward the absorbent layer, and then the air is discharged from the air outlets.

[0013] Furthermore, the aforementioned dehumidifier also includes a control module, and the fan is electrically connected to the control module.

[0014] Furthermore, the control module is provided with a communication interface, and the connection end of the communication interface is exposed from the housing.

[0015] Furthermore, a level switch electrically connected to the control module is installed inside the water tank, and a level indicator light electrically connected to the control module is also installed on the housing.

[0016] Furthermore, the housing is provided with a water-absorbing layer mounting groove, the water-absorbing layer is disposed in the water-absorbing layer mounting groove, the top end of the water-absorbing cotton core passes through the bottom of the water-absorbing layer mounting groove and connects to the water-absorbing layer, the fan is located above the water-absorbing layer mounting groove, and the air outlet is connected to the upper space of the water-absorbing layer mounting groove.

[0017] Furthermore, a retaining edge is provided at the upper end of the inner side wall of the water-absorbing layer mounting groove. After the water-absorbing layer is placed in the water-absorbing layer mounting groove, the retaining edge presses against the edge of the water-absorbing layer.

[0018] Furthermore, a number of fixing screws are provided on the baffle, and the fixing screws pass through the baffle and the edge of the absorbent layer in sequence and are fixed to the bottom of the absorbent layer mounting groove.

[0019] Furthermore, a water-absorbing cotton core fixing seat is provided at the bottom of the water tank, and the bottom end of the water-absorbing cotton core is fixed on the water-absorbing cotton core fixing seat.

[0020] Furthermore, the inner wall of the through hole is tightly fitted with the outer wall of the absorbent cotton core.

[0021] Furthermore, the absorbent layer is a fiber absorbent foam.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention, through the cooperation of a fan and a water-absorbing layer, enables the humidification amount and time to meet the humidification requirements of the dehumidification cabinet, without damaging the items inside the dehumidification cabinet due to excessively rapid humidification.

[0024] 2. Since the top of the absorbent cotton core enters from the bottom of the absorbent cotton core mounting hole and exits from the top of the absorbent cotton core mounting hole, after the absorbent layer absorbs water and expands, the absorbent layer can still maintain full contact with the absorbent cotton core, ensuring that the absorbent layer is always fully moist, which can accelerate the humidification speed in the dehumidifying cabinet.

[0025] 3. The inner wall of the through hole fits tightly with the outer wall of the absorbent cotton core, so that the water in the water tank will not leak when the water tank is tilted, ensuring the safety of the items in the dehumidifying cabinet and providing high safety performance.

[0026] 4. After the absorbent layer absorbs water and expands, since a baffle is provided at the upper end of the inner side wall of the absorbent layer mounting groove, after the absorbent layer is placed in the absorbent layer mounting groove, the baffle presses against the edge of the absorbent layer, so the middle part of the absorbent layer will bulge upward, increasing the contact area of ​​the humidified air and further improving the humidification speed.

[0032] like Figures 1 to 5As shown, in this embodiment, the present invention includes a water tank 1, a water inlet 2, a sealing plug 3 at the water inlet 2, and a through hole 4 at the top of the water tank 1. The dehumidifier also includes an absorbent cotton core 5. In this embodiment, the inner wall of the through hole 4 is tightly fitted with the outer wall of the absorbent cotton core 5. Even when the water tank 1 is tilted, the water in the water tank 1 will not leak, ensuring the safety of the items inside the dehumidifier and providing high safety performance. The bottom end of the absorbent cotton core 5 passes through the through hole 4 and enters the water tank 1, while the top end of the absorbent cotton core 5 protrudes from the through hole 4. The dehumidifier also includes an absorbent layer 6, which is a fiber absorbent cotton. The absorbent layer 6 is laid flat above the water tank 1. The absorbent layer 6 has an installation hole 7 for the absorbent cotton core. The top end of the absorbent cotton core 5 enters from the bottom of the installation hole 7 and exits from the top of the installation hole 7. The inner wall of the cotton core mounting hole 7 fits tightly with the outer wall of the absorbent cotton core 5. A housing 8 is also provided on the top of the water tank 1, and a fan 9 is mounted on the housing 8. The fan 9 is located above the absorbent layer 6, and the top of the housing 8 has an air inlet 10 adapted to the fan 9. Three air outlets 11 are provided on the side of the housing 8. The fan 9 draws in air from outside the housing 8 through the air inlet 10 and blows it towards the absorbent layer 6, then the air is discharged from the air outlets 11. The air inlet 10 is matched to the air intake of the fan 9, and the total size of the three air outlets 11 is smaller than the total size of the air inlet 10. This accelerates the airflow speed and the exchange of moisture between the air and the absorbent layer 6, effectively improving the humidification speed.

[0033] In this embodiment, the dehumidifier for a dehumidifying cabinet further includes a control module 12, and the fan 9 is electrically connected to the control module 12. In this embodiment, the control module 12 is provided with a communication interface 13, the connection end of which protrudes from the housing 8. The control module 12 can control the working time and rotation speed of the fan 9, and can interface with the existing control board of the dehumidifying cabinet through the communication interface 13, facilitating upgrades. When using the dehumidifier for a dehumidifying cabinet of this invention, no modification to the original dehumidifying cabinet is required, making it very convenient to use.

[0034] In this embodiment, a level switch 14 electrically connected to the control module 12 is installed inside the water tank 1, and a level indicator light 15 electrically connected to the control module 12 is also installed on the housing 8. When the control module 12 detects that the liquid level in the water tank 1 is lower than the lowest level that the level switch 14 can detect, the control module 12 controls the level indicator light 15 to light up. The user can see the lit level indicator light 15 through the glass door of the dehumidifier, which effectively reminds the user to add water.

[0035] In this embodiment, the housing 8 has a water-absorbing layer mounting groove 16, and the water-absorbing layer 6 is disposed within the water-absorbing layer mounting groove 16. The top end of the water-absorbing cotton core 5 passes through the bottom of the water-absorbing layer mounting groove 16 and connects to the water-absorbing layer 6. The fan 9 is located above the water-absorbing layer mounting groove 16, and the air outlet 11 communicates with the upper space of the water-absorbing layer mounting groove 16. In this embodiment, a retaining edge 17 is provided at the upper end of the inner sidewall of the water-absorbing layer mounting groove 16. After the water-absorbing layer 6 is disposed within the water-absorbing layer mounting groove 16, the retaining edge 17 presses against the edge of the water-absorbing layer 6. After the water-absorbing layer 6 absorbs water and expands, because the retaining edge 17 is provided at the upper end of the inner sidewall of the water-absorbing layer mounting groove 6 and the retaining edge 17 presses against the edge of the water-absorbing layer 6, the middle part of the water-absorbing layer 6 will bulge upwards, such as... Figure 5 As shown, the contact area of ​​the humidified air is increased, further improving the humidification speed.

[0036] In this embodiment, four fixing screws 18 are provided on the retaining edge 17. The fixing screws 18 pass through the retaining edge 17 and the edge of the absorbent layer 6 in sequence and are fixed to the bottom of the absorbent layer mounting groove 16. The four fixing screws 18 respectively fix the four edges of the absorbent layer 6.

[0037] In this embodiment, a water-absorbing cotton core fixing seat 19 is provided at the bottom of the water tank 1, and the bottom end of the water-absorbing cotton core 5 is fixed on the water-absorbing cotton core fixing seat 19. The water-absorbing cotton core fixing seat 19 can improve the stability of the water-absorbing cotton core 5 during use, avoid deformation and bending after absorbing water, and ensure that the water at the bottom of the water tank 1 is absorbed.

[0038] The working principle of this invention is as follows: During use, the user injects appropriate water into the water tank 1. The absorbent cotton core 5 absorbs the water in the water tank 1 and transfers it to the absorbent layer 6. The absorbent layer 6 then becomes fully saturated with water. The two sides of the absorbent layer 6 are fixed, while the middle bulges upwards. The humidifier of this invention is then placed in a dehumidifying cabinet. The control board of the dehumidifying cabinet is connected to the communication interface 13 via a cable. The user can then control the humidifier through the control board of the dehumidifying cabinet itself. After the fan 9 is started, it draws relatively dry air from inside the dehumidifying cabinet outside the casing 8 through the air inlet 10 and blows it towards the absorbent layer 6. The relatively dry air exchanges with the absorbent layer 6, and then the moist air is discharged from the air outlet 11, thus achieving the technical effects of large humidification capacity, moderate humidification time, good humidification effect, and high safety performance.

[0039] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
