Description

Technical Field

[0001] This utility model relates to the technical field of drying devices, specifically a dehumidifying and drying device with preheating function. Background Technology

[0002] A dehumidifier dryer is a device specifically designed for dehumidifying and drying items. It typically contains a heating system, a circulating air system, and a dehumidifier. During operation, the heating system heats the interior of the cabinet, accelerating the evaporation of moisture from the surface of items into water vapor. The circulating air system continuously circulates air, delivering the water vapor-containing air to the dehumidifier, where the moisture is removed through condensation or adsorption. The dried air is then circulated back into the cabinet, repeating this cycle to achieve rapid and efficient removal of moisture from items. It can be used to dry clothing, shoes, paintings, calligraphy, medicinal herbs, electronic products, and other moisture-sensitive items, preventing them from becoming damp, damaged, moldy, or spoiled.

[0003] Many people have experience using dehumidifiers in daily life, but a common and frustrating problem with current dehumidifiers on the market is their long start-up time. After placing items inside, it often takes a long time for the machine to actually begin the drying process. During this extended wait, the items remain damp. Fresh ingredients, precious medicinal herbs, or easily oxidized electronic products, if not dried promptly, will easily spoil or become damaged due to the continuous moisture. This not only results in waste but also causes considerable inconvenience. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a dehumidifying and drying device with preheating function that can be quickly started during the drying of items, thereby reducing the time the items are damp.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a dehumidifying and drying device with preheating function, comprising:

[0006] The drying chamber has a baffle door and control panel on the front and a blower assembly on the rear. Inside, there are several drying trays.

[0007] The preheating component is fixedly installed above the drying chamber and includes an exhaust fan, an electric heating plate and a temperature sensor. The electric heating plate is located at the air outlet of the exhaust fan, and a filter plate is provided at the air inlet of the exhaust fan. The temperature sensor is fixedly installed on the inner wall of the drying chamber and is electrically connected to the exhaust fan.

[0008] A ventilation assembly, fixedly installed on the side wall of the drying chamber, includes an exhaust duct and a second filter plate, wherein the second filter plate is located at the end of the exhaust duct away from the drying chamber.

[0009] Furthermore, anti-slip pads are provided at the four corners of the bottom of the drying chamber.

[0010] Furthermore, the barrier door is equipped with a transparent observation window.

[0011] Furthermore, the blower assembly includes a blower located inside the drying chamber and a filter screen located on the rear side wall of the drying chamber, wherein an electric heating strip is provided on the inner side of the filter screen.

[0012] Furthermore, the drying carrier plate can be slidably pulled out of the drying chamber, the side wall of the drying chamber is provided with a guide seat matching the drying carrier plate, the front side of the drying carrier plate is provided with a handle, and the drying carrier plate is provided with several ventilation slots.

[0013] Furthermore, the control panel is equipped with knobs for controlling the working time of the blower assembly, the working temperature of the blower assembly, and the working time of the exhaust fan, and the control panel is also equipped with a display screen.

[0014] Compared with existing technologies, the advantages of this invention are as follows: When the exhaust fan is working, outside air enters after being filtered through a filter plate, removing dust and other impurities to ensure clean air entering the drying chamber. The air is heated as it passes through the heating plate. A temperature sensor monitors the temperature inside the drying chamber in real time and is electrically connected to the exhaust fan, allowing for precise control of the heating process. This ensures the drying chamber reaches a suitable preheating temperature before items are placed inside. The exhaust fan has low power consumption, and the heating plate heats up quickly, enabling rapid heating within the drying chamber.

[0015] When items need drying, the device can quickly start the drying process since preheating has already been completed. The blower in the air-blowing unit promotes airflow within the drying chamber, and the electric heating strips heat the air, ensuring full contact between the hot air and the items, accelerating moisture evaporation. Ventilation slots on the drying trays facilitate air circulation, allowing the hot air to better reach all parts of the items. The exhaust ducts in the ventilation unit promptly remove humid air, and the filter plate prevents external dust from entering. The preheating and blower units work together to enable the drying process to start rapidly, significantly reducing the time items remain damp and improving drying efficiency.
