Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of humidity detection, in particular to a novel clothing dryness and humidity detection device. Background Art
[0002] Most existing laundry processing devices have the function of determining the humidity of clothes. Due to the great convenience it brings to users during the laundry processing process, this function has been widely used and will become an important trend in future production and life.
[0003] As clothes are processed in the device, the moisture content in the clothes changes. Most existing devices usually use contact resistance measurement or indirect measurement methods to determine the humidity of clothes.
[0004] The most commonly used method for detecting clothing humidity in various clothing processing devices is the resistance measurement method. The patent discloses a humidity detection device for a clothes dryer and a clothes dryer. The humidity detection device includes a metal cylinder with an insulated metal sheet mounted on the inner wall of the metal cylinder. The metal cylinder and the metal sheet serve as two electrodes of the humidity detection device. Specifically, two or more metal electrode sheets are provided at a predetermined interval within the clothing container of the clothing processing device. These metal electrode sheets are connected to a detection circuit. By measuring the resistance between the metal sheets, the moisture content of the clothing can be roughly estimated, thereby determining the dryness or wetness.
[0005] Existing technical solutions mainly use direct or indirect contact of metal electrodes to calculate the resistance value to determine the wetness of clothing. However, there are many shortcomings in the process of use, mainly manifested as follows:
[0006] 1) Common resistive detection solutions require the metal electrode to be in contact with the clothing and exposed inside the container. This results in a lack of insulation between the metal electrode and the clothing container. During operation, moisture from the clothing can easily diffuse into the detection circuit through holes or gaps in the assembly, causing damage.
[0007] 2) Commonly used resistive sensing solutions detect clothing that is in contact with the metal electrode and cannot measure the internal wetness of clothing. This can lead to incorrect judgments about the internal wetness of clothing made of different materials or with multiple layers, resulting in low humidity measurement accuracy.
[0008] 3) The metal electrode is exposed in the container, which can easily transmit static electricity on the clothes to the circuit through the metal electrode, causing interference or damage to the circuit.
[0009] 4) The metal electrode is exposed in the container, and the additives used in the clothing processing process will remain on the surface of the metal electrode, thereby affecting the accuracy of clothing humidity measurement. Utility Model Content
[0010] In order to solve the above technical problems, the purpose of the present invention is to provide a new type of clothing dryness and wetness detection device.
