[0003] In the prior art, the air is dehumidified by continuously turning on the dehumidifier to reduce the water vapor content in the air. However, if the dehumidifier is still turned on when the indoor air has been dehumidified, it will cause a waste of resources and increase additional energy consumption. Excessive dehumidification of the indoor air can also easily cause discomfort to the human body. Since some dehumidifiers often work in a humid environment, humid air often needs to enter the interior. The internal layout of the dehumidifier is not reasonable, which can easily cause damage to the internal circuit, main control device, and compression device of the dehumidifier.

[0039] Example

[0040] The present application embodiment provides a dehumidifier, such as Figures 1 to 3 As shown, it includes: a housing 1, a main control device 2, and a compression device 3, an evaporation device 4, a condensation device 5, and a fan 6 which are respectively connected to the main control device 2 for communication;

[0041] The housing 1 is provided with a baffle plate 13, which divides the internal space of the housing 1 into a first space 71 and a second space 72; the first space 71 is used for gas circulation and for accommodating the evaporation device 4, the condensation device 5 and the fan 6, and the second space 72 is used for accommodating the main control device 2 and the compression device 3;

[0042] The air entering the dehumidifier usually contains moisture, which can easily cause corrosion to the internal components and circuits of the dehumidifier, affecting its service life.

[0043] The setting of the blocking plate 13 divides the internal space into a first space 71 and a second space 72, wherein the first space 71 is for gas circulation, and the second space 72 is a space blocked by the blocking plate 13 and difficult for gas to enter. The main control device 2 and the compression device 3 that do not need to be in direct contact with the gas are arranged in the second space 72, thereby effectively reducing the influence of water vapor corrosion, protecting the main control device 2 and the compression device 3, and thus extending the service life of the main control device 2 and the compression device 3.

[0044] In addition, the first space 71 is separated from the second space 72, and the second space 72 can also block the propagation of noise, thereby helping to reduce the overall noise of the dehumidifier and optimize the user experience.

[0045] A fan bracket 61 is disposed in the first space 71, and the fan bracket 61 divides the first space 71 into a first area 711 and a second area 712. The first area 711 is located on a side of the fan bracket 61 away from the evaporation device 4, and the second area 712 is located on a side of the fan bracket 61 close to the evaporation device 4. The fan 6 is located in the first area 711, and the evaporation device 4 and the condensation device 5 are located in the second area 712.

[0046] Specifically, the evaporation device 4 and the condensation device 5 need to be in direct contact with the airflow to be dehumidified, while the fan 6 is not necessary. The fan 6 only needs to be in contact with the dehumidified airflow and play a traction role on the dehumidified airflow. The evaporation device 4, the condensation device 5 and the fan 2 are arranged in different areas within the first space 71. This can further extend the service life of the dehumidifier without affecting the dehumidification efficiency.

[0047] The housing 1 is further provided with an air inlet 11 and an air outlet 12 to form an air duct from the air inlet 11 to the air outlet 12 . The air inlet 11 is distributed in the second area 712 , and the air outlet 12 is distributed in the first area 711 .

[0048] The position setting of the fan bracket 61 optimizes the internal structure layout of the first space 71, isolates the fan 6 from the evaporation device 4 and the condensation device 5, and can also reduce the interference of the fan 6 on the evaporation device 4 and the condensation device 5 when the fan 6 is running, thereby ensuring the normal operation and stable performance of the evaporation device 4 and the condensation device 5.

[0049] The positions of the air inlet 11 and the air outlet 12 are set to optimize the air flow path. The air inlet 11 and the air outlet 12 on the housing 1 introduce the air from the air inlet 11 into the second area 712 through the air duct, and then exhaust it from the first area 711. This allows the air to flow effectively around the evaporation device 4 and the condensation device 5, increasing the efficiency and performance of the dehumidification system. The fan 6 is separated from the evaporation device 4 and the condensation device 5, and the possibility of the noise and vibration generated by the fan 6 when running being transmitted to the evaporation device 4 and the condensation device 5 can also be reduced.

[0050] More specifically, the air inlet holes 11 are distributed in the second area 712, and the air outlet holes 12 are distributed in the first area 711, so that the air inlet holes 11 and the air outlet holes 12 are not arranged in the area where the fan bracket 61 is located. This can avoid the escape of undehumidified airflow to a certain extent, thereby ensuring the dehumidification quality to a certain extent.

[0051] Furthermore, if Figure 1 As shown, the surface of the housing 1 provided with the air inlet 11 is the first surface 81, and the surface provided with the air outlet 12 is the second surface 82;

[0052] The area of ​​the first surface 81 is not less than the area of ​​the second surface 82 .

[0053] The area of ​​the first surface 81 is larger than the area of ​​the second surface 82, which helps to increase the amount of incoming air, so that the incoming air can effectively contact the evaporation device 4, and the water vapor in the air condenses with the condensation to complete the dehumidification of the air, thereby improving the dehumidification efficiency of the dehumidifier;

[0054] In addition, since the first surface 81 where the air inlet 11 is located is larger than the second surface 82 where the air outlet 12 is located, good air flow can be maintained, so that during the operation of the dehumidifier, air can flow smoothly through the evaporation device 4, thereby reducing the required operating speed of the fan 6 and the noise generated by the fan 6 when working, and can also achieve the same dehumidification effect as before.

[0055] Furthermore, the first surface 81 and the second surface 82 are two adjacent surfaces.

[0056] It can be understood that the positions of the air inlet 11 and the air outlet 12 are usually set to optimize the air flow path. By separating the air inlet 11 and the air outlet 12 and placing them on adjacent surfaces, the air flow inside the dehumidifier can be more effectively designed and controlled to maximize the dehumidification efficiency and performance.

[0057] It can also prevent the air inlet 11 and the air outlet 12 from being arranged on opposite surfaces, which may cause the air to form a short-circuit effect inside, and prevent a part of the air that has not been dehumidified from directly re-entering the room through the air outlet 12 without going through the dehumidifier.

[0058] Since the first surface 81 and the second surface 82 are two adjacent surfaces, the flow path of the airflow inside the dehumidifier can be improved, the flow speed of the airflow can be slowed down, and the residence time of the gas inside the evaporator can be increased, so that the incoming gas can fully contact the evaporation device 4, thereby optimizing the dehumidification effect.

[0059] Furthermore, a through hole 611 matching with the fan 6 is provided on the fan bracket 61 , so that the fan 6 can be mounted in the housing 1 .

[0060] The fan 6 is fixed to the shell 1 by a fan bracket 61, so that the fan 6 can maintain a stable relative position, which can to a certain extent prevent the fan 6 from moving or generating noise due to vibration or instability during operation; the wind generated by the fan 6 passes through the through hole 611, which can effectively guide and manage the incoming air, thereby optimizing the internal air circulation effect, and further enhancing the dehumidification effect of the dehumidifier.

[0061] Furthermore, if Figure 1 As shown, a water collecting tank 9 is provided at one side of the bottom of the shell 1 close to the evaporation device 4 , and the water collecting tank 9 is provided along the length direction of the evaporation device 4 .

[0062] The water collection tank 9 is arranged along the length of the evaporation device 4, which can effectively collect the water condensed from the evaporation device 4, and can prevent the water from dripping onto the surface or floor around the device to a certain extent, keeping the environment dry and clean. Collecting the condensed water in the water collection tank 9 can prevent the water from accumulating inside or around the device, thereby preventing water damage to the device itself during long-term use. The water collection tank 9 design can also make drainage more convenient and controllable. By centrally collecting and managing condensed water, a more effective drainage system can be designed to ensure that the water is safely discharged to a designated place, such as a drainage pipe or container.

[0063] Furthermore, a humidity monitoring device (not shown in the figure) is provided, which is placed between the air inlet 11 and the evaporation device 4 and located on a side close to the air inlet 11 to monitor the humidity of the gas entering the air duct.

[0064] The humidity monitoring device can monitor the humidity of the air entering the air duct in real time. By obtaining humidity data instantly, the dehumidifier can adjust the working mode and dehumidification capacity according to the current air humidity to achieve the best dehumidification effect.

[0065] By adjusting the operation of the dehumidifier based on real-time humidity data, the device can adjust operating hours and energy consumption according to actual needs, thereby saving energy and reducing operating costs.

[0066] Automatically monitoring and adjusting the humidity level can improve the user experience. The user does not need to manually adjust the device settings, but relies on the intelligent main control device 2 to keep the environment within a comfortable and ideal humidity range.

[0067] Furthermore, the fan 6 includes a cross-flow fan, the condensing device 5 includes a fin-type condensing device, the evaporating device 4 includes a fin-type evaporating device, and the larger outer surface of the evaporating device 4 is arranged toward the air inlet 11 .

[0068] Crossflow fans usually provide higher air flow and have lower energy consumption. They can effectively promote the flow of air inside the dehumidifier and help to quickly discharge moisture and heat. Crossflow fans usually have lower noise and vibration during operation, which can make the dehumidifier quieter and more stable during operation, thereby helping to reduce the overall energy consumption and noise of the dehumidifier and improve energy utilization.

[0069] The design of the finned condenser and finned evaporator can provide a larger surface area. The larger outer surface of the evaporator 4 is arranged toward the air inlet 11, so that the incoming air can fully contact the evaporator 4 to enhance the dehumidification efficiency. The design of the fins allows more surface area to be used for heat and mass transfer under the same volume, thereby improving the overall heat exchange efficiency. The design of the finned condenser 5 and evaporator 4 also helps to reduce noise and vibration during machine operation.

[0070] Furthermore, if Figure 1 and Figure 2 As shown, an adjustable mounting foot pad 18 is provided on a side of the housing 1 away from the air outlet 12 .

[0071] The adjustable mounting foot pads 18 can be adjusted according to the height or imbalance of different floors, so that the dehumidifier can maintain stable support and balance during installation, and can reduce vibration and noise caused by imbalance. The design of the adjustable mounting foot pads 18 can also effectively prevent the dehumidifier from sliding or moving on the ground, especially under the influence of vibrations generated during the operation of the equipment, which helps to ensure the safe operation of the equipment while reducing the risk of damage to the equipment and the surrounding environment. In addition, the adjustable mounting foot pads 18 can absorb and reduce the effect of vibrations transmitted to the ground during the operation of the dehumidifier, thereby reducing the noise generated by the equipment, which can improve the user experience and reduce interference from the surrounding environment.

[0072] Furthermore, if Figure 2 As shown, the housing 1 includes a front housing 14 and a rear housing 15;

[0073] The front shell 14 is provided with a first snap-fit ​​structure 16 , and the rear shell 15 is provided with a second snap-fit ​​structure 17 , so as to realize a detachable connection between the front shell 14 and the rear shell 15 .

[0074] The front shell 14 and the rear shell 15 are detachably connected through the snap connection of the first snap connection structure 16 and the second snap connection structure 17, making it easier to disassemble the front shell 14 and the rear shell 15 for cleaning and maintenance, thereby improving the convenience and efficiency of operation.

[0075] The precise design of the first snap-fit ​​structure 16 and the second snap-fit ​​structure 17 enables the front shell 14 and the rear shell 15 to fit tightly when connected, thereby optimizing the appearance and overall design of the dehumidifier, which not only improves the aesthetics of the product, but also increases the market appeal of the product.

[0076] Furthermore, a filter screen (not shown in the figure) is provided on a side of the front shell 14 facing away from the air inlet hole 11 .

[0077] The filter can effectively prevent fine particles such as dust, hair, pollen, etc. in the air from entering the dehumidifier, which helps protect the mechanical parts, electronic components and core components inside the dehumidifier, extending its service life and stability.

[0078] Filtering the air through the filter can reduce the accumulation of dust and other impurities inside the device, which helps to keep the dehumidifier working efficiently. After the clean air flows into the device, the factors that may affect the dehumidification efficiency are reduced.

[0079] The filter can also help purify the air inhaled from the air inlet 11 and prevent dust and other pollutants from entering the indoor air, which is crucial to the health and comfort of the user, especially in an environment where the dehumidifier needs to run for a long time.

[0080] Furthermore, the evaporation device 4 is provided with a refrigerant for dehumidifying the gas in the air duct by vaporizing the refrigerant. The compression device 3 is respectively connected to the evaporation device 4 and the condensation device 5 through pipelines for compressing the vaporized refrigerant. The condensation device 5 is connected to the evaporation device 4 for obtaining the compressed refrigerant from the compression device 3 and liquefying the refrigerant and transporting it back to the evaporation device 4.

[0081] The provision of the fan 6 can increase the circulation speed of the gas, thereby improving the dehumidification efficiency of the dehumidifier. The fan 6 can also play a pulling and guiding role on the flow of the gas.

[0082] Among them, the moisture in the air can be effectively removed through the cooperation of the evaporation device 4 and the condensation device 5. The evaporation device 4 absorbs water vapor in the air through the vaporization of the refrigerant, and processes the wet air into relatively dry air, thereby achieving a dehumidification effect;

[0083] The refrigerant absorbs heat through the vaporization process in the evaporator 4, takes the heat away, and pre-condenses the water vapor in the air, thereby reducing the relative humidity of the air. The compression device 3 compresses the refrigerant gas to increase its temperature and pressure so that it can be condensed in the condensing device 5. Such heat transfer and processing process can improve the energy efficiency ratio of the dehumidifier and save energy through effective thermodynamic conversion.

[0084] The main control device 2 is used to obtain the air humidity state and adjust the refrigerant dosage and the rotation speed of the fan 6.

[0085] It can be understood that by obtaining the air humidity state in real time through the main control device 2, and adjusting the operating parameters of the dehumidifier, such as the amount of refrigerant and the speed of the fan 6, to achieve the set humidity level, it is possible to ensure that the indoor humidity is stable within a comfortable or appropriate range, and avoid the impact of excessive humidity or dryness on human health and the environment. Adjusting the working parameters according to the real-time humidity state can also optimize the efficiency of energy use. By controlling the amount of refrigerant and the speed of the fan 6, it is possible to reduce energy consumption while meeting the humidity requirements and improve the energy efficiency of the dehumidifier.

[0086] The embodiments of the present application have at least the following beneficial effects:

[0087] The present application provides a dehumidifier, which optimizes the internal spatial layout of the dehumidifier, and can effectively avoid moisture damage to the components by reasonably planning the positions of important internal components; specifically, the space division is optimized through the blocking plate 13 and the fan bracket 61, and the evaporation device 4, the condensation device 5 and the fan 6 that must be in contact with the air circulation are arranged in the same space, and the main control device 2 and the compression device 3 that do not necessarily have to be in contact with the air circulation and are susceptible to corrosion and damage are arranged in another separated space.

[0088] Those skilled in the art will appreciate that the modules in the device in the implementation scenario can be distributed in the device in the implementation scenario according to the implementation scenario description, or can be changed accordingly and located in one or more devices different from the implementation scenario. The modules in the above implementation scenario can be combined into one module, or can be further split into multiple sub-modules.

[0089] The above application serial numbers are for description only and do not represent the advantages or disadvantages of the implementation scenarios.

[0090] The above disclosure only discloses several specific implementation scenarios of the present application. However, the present application is not limited thereto, and any changes that can be conceived by technicians in this field should fall within the scope of protection of the present application.
