The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices or methods consistent with some aspects of the present application detailed in the appended claims.

[0052] Hereinafter, the technical solutions of the embodiments of the present utility model will be clearly and completely described with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments described in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present utility model.

[0053] As Figure 2 shown, a semiconductor refrigeration sheet dehumidifier of the present utility model includes a drainage system 1, an air circulation system 2, a dehumidification system 3, a heat drying system 4, a control system 5 and a housing 6.

[0054] A semiconductor refrigeration sheet dehumidifier of the present utility model is a comprehensive humidity control device that integrates multiple key systems to achieve efficient dehumidification; the drainage system 1 is responsible for collecting and discharging condensed water; the air circulation system 2 ensures that the humid air can flow evenly through the dehumidifier and be fully processed; the dehumidification system 3 uses semiconductor refrigeration sheet technology to condense the water vapor in the air by reducing the temperature, thereby reducing the humidity; the heat drying system 4 uses the heat generated by the semiconductor to dry the air and further remove moisture; the control system 5 monitors the environmental humidity and intelligently adjusts the dehumidification efficiency; and the housing 6 protects the internal components and provides an aesthetically pleasing and reasonably structured outer shell.

[0055] In a preferred embodiment of the present utility model, as Figure 1 shown, the housing 6 includes a base 61, a cylinder 62 and an air guide cap 63. The air guide cap 63 is disposed at the upper end of the cylinder 62, and the base 61 is disposed at the lower end of the cylinder 62.

[0056] The housing 6 is the external structure of the semiconductor refrigeration sheet dehumidifier of the present utility model, mainly composed of the base 61, the cylinder body 62 and the air guide cap 63; these three parts are assembled together by a tight connection method to form a complete and stable housing structure.

[0057] The base 61 is preferably a cylinder, the diameter of the upper circle is slightly smaller than that of the lower circle. As the support base of the entire housing, the base 61 is stably arranged at the lower end of the cylinder body 62, which not only provides stable support for the entire dehumidifier, but also facilitates the layout of the drainage system 1, because the placement space for drainage components such as the water collection box 11 is reserved inside the base 61.

[0058] The cylinder body 62 is the main part of the housing 6, preferably a cylindrical body. The thickness of the cylinder body 62 is not less than 3 mm and is fixedly connected to the base 61 to form the core structure of the dehumidification mechanism components; as Figure 2 shown, the air circulation system 2, the dehumidification system 3, the heat drying system 4 and the control system 5 and other key components are accommodated inside the cylinder body 62; these systems are tightly connected to the cylinder body 62 through precise installation and wiring to ensure the normal operation of the dehumidifier.

[0059] According to Figures 1 to 3 it can be known that the air guide cap 63 is preferably an inverted cone, the maximum diameter of the air guide cap 63 is equal to the maximum diameter of the base 61, the bottom of the inverted cone is a cross-cut plane without a cone tip, and the air guide cap 63 is fixedly arranged at the upper end of the cylinder body 62, which plays a role in guiding and optimizing air flow; the setting of the air guide cap 63 is closely related to the air circulation system 2. After the humid air enters the dehumidifier, it passes through the dehumidification system 3, the heat drying system 4, the air outlet 25 and the air guide cap 63 to form a diffusion wide angle to release dry air around.

[0060] The base 61, the cylinder body 62 and the air guide cap 63 are preferably fastened and connected with screws, and can also be connected by a snap connection method.

[0061] In another preferred embodiment of the present utility model, the drainage system 1 is arranged inside the base 61, including a water collection box 11, a drainage port 13 and a water leakage hopper 14. The water leakage hopper 14 is communicated with the water collection box 11, and the drainage port 13 is arranged on the water collection box 11 for discharging the collected condensed water.

[0062] The drainage system 1 is an essential part of the semiconductor refrigeration sheet dehumidifier of the present utility model, responsible for processing and discharging the condensed water generated during the dehumidification process; the drainage system 1 is arranged inside the base 61, making full use of the internal space of the base 61 and facilitating the collection and discharge of condensed water at the same time.

[0063] As Figure 3 shown, the drainage system 1 mainly consists of the water collecting box 11, the drainage port 13 and the water leakage hopper 14; the upper diameter of the water leakage hopper 14 is larger than the lower diameter, the upper diameter is arranged below the position where condensed water is generated, and the lower diameter is communicated with the water collecting box 11 to ensure that the water droplets dripping from the temperature difference condensation plate 32 can smoothly flow into the water collecting box 11.

[0064] The water collecting box 11, as a container for collecting condensed water, is preferably a square box, which can be a closed box body or an upper open box body. Its material is preferably integrally formed by plastic and has enough capacity to store condensed water; the drainage port 13 is arranged on the water collecting box 11. When the condensed water in the water collecting box 11 reaches a certain amount, it can be discharged through this drainage port 13.

[0065] In another preferred embodiment of the present utility model, through Figure 2 、 Figure 3 it can be known that the dehumidification system 3 is arranged in the middle inside the cylinder body 62, including two parts, the semiconductor refrigeration sheet 31 and the temperature difference condensation plate 32. The semiconductor refrigeration sheet 31 generates a temperature difference on its two sides by applying a direct current, used to cool the flowing humid air; the temperature difference condensation plate 32 is fixedly connected to the cold end of the semiconductor refrigeration sheet 31.

[0066] Specifically, the dehumidification system 3 is the core component of the semiconductor refrigeration sheet dehumidifier of the present utility model, responsible for removing moisture in the air; this system is arranged in the middle position inside the cylinder body 62, and such an arrangement is conducive to the uniform flow of humid air and effective dehumidification.

[0067] The dehumidification system 3 mainly consists of the semiconductor refrigeration sheet 31 and the temperature difference condensation plate 32. The temperature difference condensation plate 32 is formed by multiple metal guide plates arranged vertically around the center, and the bottom of the metal guide plate inclines from the outer corner edge to the inner corner edge, so that the condensed water droplets gather towards the center of the metal guide plate for collection. The metal guide plate is preferably an aluminum plate or an aluminum sheet, and its surface is smooth; the semiconductor refrigeration sheet 31 is a square body and is used in combination with multiple pieces. Its installation form is that the cold end is downward and the hot end is upward and fixedly installed. The specific installation method is silicone grease adhesion plus screw fastening; the semiconductor refrigeration sheet 31 is the core of the dehumidification system. When a direct current is applied to it, a significant temperature difference will be generated on its two sides, with one side of the cold end getting cold and one side of the hot end getting hot.

[0068] The temperature difference condensation plate 32 is fixedly connected to the cold end of the semiconductor refrigeration sheet 31. The fixed connection method is silicone grease bonding plus screw fastening, which improves its conduction efficiency, enabling the water vapor in the flowing humid air to quickly and continuously condense into water droplets when encountering the cold condensation plate, and the dehumidification effect is more significant.

[0069] In another preferred embodiment of the present utility model, through Figures 1 to 3 As can be seen, the air circulation system 2 includes a fan 21, a wind guide cover 22, a breathable net 24, an air inlet 25, and an air outlet 26. The breathable net 24 is a high-density mesh heat-insulating and breathable net. The fan 21 guides the humid air to flow towards the temperature difference condensation plate 32 through the wind guide cover 22, causing the water vapor in the air to condense into water droplets and drip into the water leakage hopper 14, and guiding the dehumidified air upwards through the breathable net 24 into the heat drying system 4, where it is dried and then recirculated back into the room.

[0070] The air circulation system 2 is a key component in the semiconductor refrigeration sheet dehumidifier of the present utility model. It realizes air circulation dehumidification through the cooperation of multiple components. Specifically, the fan 21 is a micro DC fan, and there are no less than 2 fans fixed on the rod frame. As a power source, it is arranged around the water collection box 11 and is responsible for guiding the humid air from the bottom of the cylinder body 62 into the dehumidifier. Under the action of the fan 21, the humid air is first brought into and passes through the wind guide cover 22, and the wind guide cover 22 can evenly disperse the wet air along the lower opening of the cylinder body 62 to the temperature difference condensation plate 32. When the humid air flows through the temperature difference condensation plate 32, due to the temperature difference effect generated by the semiconductor refrigeration sheet 31, the humid air condenses into water droplets and drips into the water leakage hopper 14 below. The air after dehumidification treatment is then guided upwards and enters the high-density mesh heat-insulating and breathable net 24. This breathable net not only has strong heat-insulating performance but also has good air permeability. The dehumidified air enters the heat drying system 4 from here, where it is further heat-dried to ensure the dryness of the air. Finally, the dry air processed by the heat drying system 4 is recirculated back into the room through the air outlet 26, thus completing the entire air circulation and dehumidification process.

[0071] In another preferred embodiment of the present utility model, as Figure 2 、 Figure 3 shown, the heat drying system 4 is arranged at the upper end of the dehumidification system 3 and includes a heat collection cover 41, a hot air pipe 42, and hot air holes 43. The heat collection cover 41 is connected to the hot end of the semiconductor refrigeration sheet 31 to provide heat source for the heat drying system 4. The hot air pipe 42 is arranged at the upper end of the heat collection cover 41, and the hot air holes 43 are arranged on the pipe wall of the hot air pipe 42.

[0072] The hot air drying system 4 is a relative space, which is arranged at the upper end of the dehumidification system 3, so that the air flowing out of the dehumidification system 3 can naturally enter the hot air drying system 4 for reprocessing. The semiconductor refrigerating sheet 31 in the dehumidification system 3 generates heat during operation, and the hot air drying system 4 just utilizes this part of heat.

[0073] Specifically, the heat collecting cover 41 is made of metal heat-conducting material. Multiple branch pipe bodies are arranged at its lower part, and the upper part is a sealed cover head. The branch pipe bodies are fixedly connected to the hot ends of the semiconductor refrigerating sheets 31, and the connection method is not limited; to ensure that the heat generated by the semiconductor refrigerating sheets 31 can be completely and effectively collected and transferred into the heat collecting cover 41; to provide a stable heat source for the hot air drying system 4.

[0074] The hot air pipe 42 is fixedly arranged at the upper end of the heat collecting cover 41, and its connection method is flange bolts or welding. The hot air pipe 42 is located on the central axis of the hot air drying system 4 and can be a rectangular pipe or a circular pipe. Its upper end is fixedly connected to the air guiding cap 63 by screws; the hot air pipe 42 is used to evenly distribute the heat accumulated in the heat collecting cover 41 upward to a larger space. To achieve this, a plurality of hot air holes 43 are arranged on the pipe wall of the hot air pipe 42. The hot air from the hot air holes 43 flows out of the pipe and is mixed with the dehumidified air to increase the temperature of the air and further remove the moisture therein.

[0075] In another preferred embodiment of the present invention, by Figures 1 to 3 It can be seen that the control system 5 includes a humidity monitoring module 51, a temperature monitoring module 52 and a control panel 53; the humidity monitoring module 51 is arranged at the air inlet 25, the temperature monitoring module 52 is arranged on the heat collecting cover 41, and the control panel 53 is arranged on the outer shell of the cylinder body 62 for convenient operation.

[0076] The control system 5 is responsible for monitoring environmental parameters and controlling the operation of the dehumidifier according to these parameters. The control system 5 mainly consists of the humidity monitoring module 51, the temperature monitoring module 52 and the control panel 53, and these parts are interconnected through circuits and data lines.

[0077] The humidity monitoring module 51 is fixedly arranged at the air inlet 25, and this position is selected based on the accurate monitoring requirement of the humidity of the air entering the dehumidifier; when the humid air enters the dehumidifier through the air inlet 25, the humidity monitoring module 51 can detect the humidity level in the air in real time. This data is crucial for the control system because it allows the control system to adjust the working state of the dehumidifier according to the environmental humidity to achieve the best dehumidification effect.

[0078] The temperature monitoring module 52 is fixedly installed on the heat collecting cover 41. Its main purpose is to accurately monitor the temperature change in the heat drying system 4. The heat drying system 4 uses the heat generated by the hot end of the semiconductor refrigeration chip to dry the air. Therefore, precise control of its temperature is crucial. The temperature monitoring module 52 continuously detects the temperature of the heat collecting cover 41 to ensure that the heat drying process is both effective and does not cause damage to the semiconductor refrigeration chip 31 due to overheating.

[0079] The control panel 53 is fixedly embedded in the outer shell in the upper middle part of the cylinder body 62, enabling users to conveniently operate and adjust the dehumidifier; the control panel 53 is the main interface for users to interact with the dehumidifier. It allows users to set the target humidity, view the current humidity and temperature readings, and start or stop the function of the dehumidifier; the control panel 53 receives and processes data from the humidity monitoring module 51 and the temperature monitoring module 52 through the internal microprocessor, and regulates the operation of the dehumidifier according to the user's settings and current environmental parameters.

[0080] In another preferred embodiment of the present utility model, the humidity monitoring module 51 is used to monitor the environmental humidity in real time and control the working current of the semiconductor refrigeration chip 31 according to the humidity value, thereby adjusting the dehumidification efficiency.

[0081] The humidity monitoring module 51 is a key component in the control system 5. It is responsible for monitoring the environmental humidity in real time and controlling the working current of the semiconductor refrigeration chip 31 according to the humidity value to achieve the purpose of adjusting the dehumidification efficiency.

[0082] First, the humidity monitoring module 51 is equipped with a high-precision humidity sensor, which can continuously detect the humidity level in the environment; the humidity sensor converts the detected humidity value into an electrical signal and then transmits it to the microprocessor of the control system 5; then, the microprocessor receives and analyzes these signals to determine whether the current humidity level meets the target humidity set by the user; if the environmental humidity is higher than the target humidity, the control system 5 will correspondingly adjust the working current of the semiconductor refrigeration chip 31.

[0083] Specifically, the control system 5 may increase the working current of the semiconductor refrigeration chip 31 to improve its refrigeration effect, thereby accelerating the condensation rate of water vapor in the air on the temperature difference condensation plate 32 and enhancing the dehumidification effect; conversely, if the environmental humidity is already lower than or close to the target humidity, the control system 5 may reduce or stabilize the working current of the semiconductor refrigeration chip 31 to reduce energy consumption and maintain an appropriate dehumidification effect.

[0084] In addition, the control system 5 also allows the dehumidifier to automatically stop or reduce the dehumidification power after reaching the humidity level set by the user, thus achieving energy conservation, environmental protection, and long service life of the equipment.

[0085] In another preferred embodiment of the present invention, according to Figure 2 、 Figure 3 it can be seen that the air circulation system 2 further includes an air filter 23 for filtering the air entering the dehumidifier to prevent dust and impurities from adhering to the dehumidification system 3.

[0086] The air filter 23 is a circular filter screen with a certain thickness, installed in the intake part of the air circulation system 2 and sleeved on the outer periphery of the water leakage hopper 14, that is, the initial position where the humid air enters the interior of the dehumidifier; the purpose is to remove dust, particles, and other potential pollutants in the air through the air filter 23 before the air contacts the dehumidification system 3.

[0087] It can be understood that when the humid air is sucked in by the fan 21 and guided into the dehumidifier through the air guide cover 22, it will first pass through the air filter 23; the air filter 23 can effectively capture and block most of the dust and impurities passing through; if these pollutants enter the dehumidification system directly without treatment, they will adhere to key components such as the semiconductor refrigeration sheet 31 and the temperature difference condensation plate 32, affecting their conduction efficiency and dehumidification performance.

[0088] By installing the air filter 23, the dehumidifier can maintain a high dehumidification efficiency during long-term operation, reduce the performance degradation caused by pollutant accumulation; at the same time, this also extends the service life of the internal components of the dehumidification system and reduces the maintenance cost.

[0089] In another preferred embodiment of the present invention, the water collection box 11 is detachable, which is convenient for cleaning and draining.

[0090] First, the detachable design means that the water collection box 11 can be conveniently removed from the dehumidifier; when the water in the water collection box 11 reaches a certain amount or needs to be cleaned, the user does not need to disassemble or move the entire dehumidifier, but only needs to simply remove the water collection box 11 from the base 61. There is a cover opening on the vertical surface of the base 61 for conveniently removing the water collection box 11. Second, this design also facilitates the drainage operation. In the traditional fixed water collection box design, the user may need to use pipes or other tools to drain the water, and the operation is relatively cumbersome. However, the detachable water collection box allows the user to directly remove it and pour out the accumulated water, making the operation simpler and more straightforward. In addition, the detachable design also makes the cleaning of the water collection box 11 easier; since it can be removed separately, the user can thoroughly clean and disinfect the water collection box without affecting other parts of the dehumidifier, ensuring the hygiene and cleanliness inside it.

[0091] In another preferred embodiment of the present utility model, Figure 2 、 Figure 3 As shown, the drainage system 1 includes a micro pump 12 and an external drainage pipe. The micro pump 12 is used to pump out the water in the water collection box 11 and discharge it to a designated position through the external drainage pipe.

[0092] The micro pump 12 is the core component of this drainage system 1 and is arranged inside the water collection box 11. Its function is to generate sufficient suction to pump out the accumulated water in the water collection box 11; the micro pump 12 is small in size and powerful in performance, capable of ensuring a stable and reliable pumping effect; when the water in the water collection box 11 reaches a certain amount or is triggered according to preset conditions, the micro pump 12 will start and begin the pumping operation; the external drainage pipe is responsible for transporting the water from the micro pump 12 to the designated discharge position; these pipes have a certain toughness and durability to adapt to different installation environments and drainage requirements; the pipes are tightly connected and leak-proof treated to ensure that the water can be discharged smoothly and avoid any form of leakage;

[0093] The operation of the entire drainage system 1 is automated. Once the water in the water collection box 11 reaches the preset water level, or the user manually activates the drainage system 1, the micro pump 12 will start working, pump out the water and discharge it to the designated position through the external drainage pipe, such as outdoors, into the sewer or other suitable drainage outlets.

[0094] In another preferred embodiment of the present utility model, the dehumidifier further includes a timing switch function, which can preset the on and off times to achieve energy conservation and environmental protection.

[0095] The timing switch function of the dehumidifier is implemented based on the internal microprocessor; users can set the specific power-on and power-off times through the control panel or the remote controller; once the setting is completed, the dehumidifier will automatically power on or off at the preset time.

[0096] The timing switch function of the dehumidifier brings great convenience and energy-saving and environmental protection advantages to users; this function enables users to preset the power-on and power-off times of the dehumidifier according to actual needs, thereby accurately controlling its operation duration and operation period; in this way, users can ensure that the dehumidifier automatically starts when needed, timely and effectively reducing the indoor humidity; at the same time, it can also automatically turn off when not needed, avoiding meaningless energy consumption and achieving the goal of energy conservation and environmental protection. This intelligent method not only improves the user experience but also responds to the call for green living, reduces power waste, reduces carbon emissions, and makes a positive contribution to environmental protection.
