Description

[0001] DEHUMIDIFIER DEVICE WITH ZEOLITE PLATES

[0002] TECHNICAL FIELD

[0003] This invention relates to dehumidifiers equipped with synthetic zeolite plates. The device is particularly suitable for use in high-humidity areas and is designed for indoor applications.

[0004] Dehumidifiers are devices that absorb moisture from the environment, thereby drying the air. Various types of dehumidifiers operate based on different principles. The most commonly used dehumidifiers include:

[0005] Condensation dehumidifiers: These devices cool the air to condense the moisture, which is then collected in a container.

[0006] Sorbent dehumidifiers: These use a sorbent material that absorbs moisture from the air.

[0007] BACKGROUND

[0008] In prior art, dehumidifiers typically utilize sorbent materials such as silica gel or clay. These materials have a specific moisture absorption capacity and need to be renewed or replaced when saturated.

[0009] Zeolite materials are known to occur naturally. With advances in technology, synthetic zeolites can now be produced through various chemical synthesis processes. Due to their atomically porous structures, zeolites exhibit high water absorption capabilities. When heated, the water within them evaporates, enabling reuse.

[0010] Patent application KR20150137739 describes a humidity regulator and its production method for humidification inside an airtight display case.

[0011] Patent CN215864548 discloses a dehumidifier for a numerically controlled machine tool, which includes a shell, a heater, a radiator, a temperature sensor, a temperature control module, and a power connection module. The heater is fixed to the shell, producing heat that the radiator uses to direct warm air into a control box.

[0012] Patent JP2002345721 focuses on removing moisture from inside a boot. Technical Problems Addressed by the Invention

[0013] Existing inventions do not address moisture removal and recovery using zeolite plates.

[0014] High humidity in indoor environments adversely affects human health and comfort. Moreover, excessive humidity causes mold growth, damaging belongings such as electronics, clothing, and furniture, while also posing health risks to humans.

[0015] While various dehumidifiers are available in the literature, no product or patent utilizing zeolite plates for indoor dehumidification has been identified.

[0016] The structural and characteristic features of this invention, along with all its advantages, are clarified through detailed descriptions and references to the accompanying figures provided below. Therefore, the evaluation should consider these figures and detailed explanations.

[0037] This invention distinguishes itself from existing dehumidifiers through its lower purchasing cost, ergonomic design for home use, modular structure for portability, and replaceable zeolite plates (10). Its manual operation prevents mechanical failures in humid environments, ensuring ease of use. The invention aims to absorb moisture through adsorption and remove it from the environment.

[0038] The dehumidifier with a zeolite plate (Figure 1) operates on 220 volts. It starts working when the power plug (7) is connected. Moisture from the environment is absorbed by the zeolite plates (10) through the front air channels (8). The built-in humidity sensor (12) measures the environmental humidity and shuts off the device automatically once the desired level is achieved. The zeolite plates (10) are then heated by the heater plates (11), causing the absorbed water to evaporate. A fan (9), fixed within the fan casing (4) which works with the heater plates (11), expels the evaporated moisture out of the device via the rear ventilation channels (5). The rear ventilation channels (5) located at the back of the device (Figure 2) expel the water vapor inside the dehumidifier (Figure 1) out of the environment.

[0039] The zeolite plates (10) and heater plates (11) are secured within the dehumidifier chassis (1) using a fixing channel (13). The device can be turned on or off using the side-mounted switch (6). The zeolite plates (10) must be replaced every 30 days during regular use. This can be done by opening the device's top cover (2) using the handle (3). The rear of the device (Figure 2) can also blow air outside through a pipe or be wall-mounted with the fan (9) facing outward. Structurally, the zeolite plates (10) consist of 3A and 4A zeolite structures (3A Zeolite Chemical Formula: K7.2Na4.8[(AIO)12(SiO2)12]mH2O; 4A Zeolite Chemical Formula: Na2O AI2O3 SiO2-4.5H2O).

[0040] Designed for home and office use, the zeolite plate-equipped dehumidifier (Figure 1) offers significant advantages as an automatic indoor appliance for environments like homes and hotels. Existing market dehumidifiers lack such a design. The low production cost of this device enhances its accessibility. Industrial Applicability

[0041] The dehumidifier with a zeolite plate (Figure 1) can be mass-produced for industrial environments and sold to consumers for use in homes, hotels, and similar locations to control humidity.

[0042] The scope of protection for this application is defined in the claims and is not limited to the examples described above. It is evident that a person skilled in the art may adapt the innovation disclosed in this invention to similar purposes in other fields by altering components or using analogous constructions. Therefore, such adaptations would lack the novelty criterion.
