Description

Technical Field

[0001] This utility model relates to the field of electronic dehumidifier structure, specifically an electronic dehumidifier with intelligent temperature and humidity monitoring function. Background Technology

[0002] In many fields, such as electronics, optics, medicine, and cultural relic preservation, items have strict requirements regarding the temperature and humidity of the storage environment. A humid environment easily leads to moisture absorption, mold growth, deterioration, and damage, severely affecting the quality and lifespan of the items. Therefore, dehumidifying cabinets, as devices that can effectively control the humidity of the storage environment, have been widely used.

[0003] Although existing electronic dehumidifiers are equipped with simple temperature and humidity sensors and dehumidification devices, they lack effective door opening and closing sensors, making it impossible to detect the door status in a timely manner. If the door is not closed for a long time or is opened and closed frequently, humid air from the outside will enter the box, causing the humidity to rise. This will cause the temperature and humidity sensor to deviate from the measurement data, reducing the reference value of the measurement data. At the same time, it will not issue an alarm in time, and the items inside the box will still be at risk of getting damp. Utility Model Content

[0004] The purpose of this invention is to provide an electronic dehumidifier with intelligent temperature and humidity monitoring. This electronic dehumidifier can sense the opening and closing status of the door in real time, and realize the separation of temperature and humidity sensor measurement data when the door is open and closed, so as to avoid the deviation of temperature and humidity sensor measurement data, ensure the reference value of temperature and humidity sensor measurement data, and at the same time, it can issue an alarm in time when the door is open for a long time to avoid the risk of moisture to the items inside the box.

[0005] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: an electronic dehumidifier with intelligent temperature and humidity monitoring function, including a cabinet body, at least one cabinet door group, and a temperature and humidity sensor, wherein the temperature and humidity sensor is disposed in the cabinet body;

[0008] An alarm device is provided on the top of the enclosure;

[0009] The controller is located on the top of the enclosure and is electrically connected to the temperature and humidity sensor, the dehumidification structure, the sensing structure, and the alarm device.

[0012] In some embodiments, the cabinet door assembly includes two symmetrically arranged cabinet doors;

[0013] The sensing structure includes two reed switches, which are located at the top of the box body near the box door assembly. The two reed switches are connected in series and electrically connected to the controller.

[0014] Two magnets are provided, one at the top of the door near the other end of the reed switch, and the other two magnets are respectively positioned corresponding to the other two reed switches.

[0015] In some embodiments, the top of the housing near the door is provided with a sensing groove, and the reed switch is provided in the sensing groove.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] refer to Figure 1-4An electronic dehumidifier with intelligent temperature and humidity monitoring function includes a cabinet body 1, at least one door assembly 2, a temperature and humidity sensor 3, a dehumidification structure 4, a sensing structure 5, an alarm device 9, and a controller 6. The cabinet body 1 serves as the main structure of the entire dehumidifier, providing support and protection for the internal components and stored items. Both the cabinet body 1 and the door assembly 2 can be made of high-quality cold-rolled steel plate, with the surface treated by multiple processes such as phosphating, electrophoretic primer, and electrostatic powder coating, giving it good corrosion resistance and aesthetics. The door assembly 2 works in conjunction with the cabinet body 1 for taking out and putting in items, and forms a relatively sealed space when closed. The temperature and humidity sensor 3 is located inside the cabinet body 1 and can monitor the temperature and humidity inside the cabinet in real time. The temperature and humidity parameters are monitored. The dehumidification structure 4 is located inside the cabinet 1, reducing humidity and maintaining a dry environment. The dehumidification structure 4 can employ various methods such as semiconductor refrigeration dehumidification, condensation dehumidification, or adsorption dehumidification, which can be selected based on actual needs. This is existing technology and will not be elaborated further. The sensing structure 5 is located between the cabinet 1 and the door assembly 2, detecting the opening and closing status of these components. The alarm device 9 is located on the top of the cabinet 1, issuing an alarm signal when the temperature and humidity inside the cabinet are abnormal or when the door 21 is not fully closed for an extended period. The alarm device 9 may include an audible and visual alarm, providing an audible and visual alert to remind the user to handle the situation promptly. The controller 6 is located on the top of the cabinet 1 and is electrically connected to the temperature and humidity sensor 3, dehumidification structure 4, sensing structure 5, and alarm device 9. The controller 6 may include a display panel, control panel, memory, processor, etc. This is existing technology and will not be elaborated further. The controller 6 receives signals from the temperature and humidity sensor 3 and sensing structure 5, and controls the operation of the dehumidification structure 4 and alarm device 9 according to a preset program and algorithm. For example, when the temperature and humidity sensor 3 detects that the humidity inside the cabinet exceeds the set upper limit, the controller 6 will activate the dehumidification structure 4 to dehumidify; when the sensing structure 5 detects that the cabinet door has not been closed for a long time, the controller 6 will control the alarm device 9 to issue an alarm.

[0028] In some embodiments, the system also includes an I / O module 7, which is electrically connected to the temperature and humidity sensor 3, the dehumidification structure 4, the sensing structure 5, and the controller 6. The I / O module 7 can serve as an interface between the controller 6 and various peripheral devices, and is responsible for signal conversion and transmission, thereby improving the stability and reliability of the system.

[0029] In some embodiments, a USB-to-RS485 module 8 is also included, which is electrically connected to the temperature and humidity sensor 3. The USB-to-RS485 module 8 converts the data collected by the temperature and humidity sensor 3 into an RS485 signal, facilitating communication and data transmission with other devices or systems. This allows the dehumidifier to be easily integrated into industrial automation control systems or IoT platforms for remote monitoring and management.

[0030] In some embodiments, the door assembly 2 includes two symmetrically arranged doors 21 for convenient access to items. One end of each door 21 is hinged to the body 1, and the other end is connected to the body 1 for opening and closing. When the two doors 21 are in contact with the body 1, a sealed connection between the two doors 21 and the body 1 is achieved. This can be achieved by using a silicone sealing ring, which is prior art and will not be described in detail here. The sensing structure 5 includes two reed switches 51 and two magnets 52. The two reed switches 51 are located at the top of the body 1 near the door assembly 2. The two reed switches 51 are connected in series and electrically connected to the controller 6. The magnets 52 are located at the top of the door 21 near the reed switches 51 and can be embedded in the mounting groove of the door 21 corresponding to the reed switch 51. They can be glued together. The two magnets 52 are respectively arranged corresponding to the two reed switches 51. When the door 21 is closed, the magnet 52 approaches the reed switch 51, and the contacts inside the reed switch 51 close. When the door 21 is open, the magnet 52 moves away from the reed switch 51, and the contacts inside the reed switch 51 open. By detecting the on / off state of the reed switch 51, the open / closed state of the door 21 can be determined. The two reed switches 51 are connected in series and electrically connected to the controller 6. This series design improves the reliability of the detection. The controller 6 will only consider the door 21 to be fully closed when both reed switches 51 are in the closed state.

[0031] In some embodiments, a sensing groove 11 is provided at the top of the end of the housing 1 near the door 21, and a reed switch 51 is provided in the sensing groove 11.

[0032] In some embodiments, the cross-section of the sensing groove 11 is convex, which can protect the reed switch 51 from external impact and ensure the effective sensing distance between the reed switch 51 and the magnet 52.

[0033] In some embodiments, a wireless transmission module is also included, which is electrically connected to the temperature and humidity sensor 3. The wireless transmission module can use wireless communication technologies such as Wi-Fi, Bluetooth, and ZigBee to transmit temperature and humidity data to the user's mobile phone, tablet, or other terminal device in real time, allowing the user to check the temperature and humidity status inside the chamber anytime and anywhere.

[0034] In some embodiments, the temperature and humidity sensor 3 can be an epitaxial PVC temperature and humidity transmitter. The epitaxial PVC temperature and humidity transmitter uses a polyvinyl chloride (PVC) shell, which has good corrosion resistance and moisture resistance, making it suitable for long-term use in humid environments. At the same time, it allows the sensor probe to be directly exposed to the air inside the chamber, enabling more accurate sensing of temperature and humidity changes and improving measurement accuracy.

[0035] The specific working principle is as follows:

[0036] Users can set the upper limit of humidity inside the chamber, the temperature and humidity alarm threshold, and the alarm time for if the chamber door 21 is not closed via controller 6. Temperature and humidity sensor 3 monitors the temperature and humidity parameters inside the chamber in real time. When temperature and humidity sensor 3 detects that the humidity inside the chamber exceeds the set upper limit, it will transmit a signal to controller 6. Controller 6 will then activate dehumidification structure 4 according to a preset program and algorithm to reduce the humidity inside the chamber and keep the environment inside the chamber dry.

[0037] The controller 6 reads the status of the two reed switches 51 in real time. When both reed switches 51 are closed, the door is considered fully closed; if either reed switch 51 is open, the door is considered not fully closed. To prevent false judgments, the controller 6 continuously monitors the status of the reed switches 51 for a period of time, such as 5 seconds. If the status remains consistent during this period, the door status is confirmed. Simultaneously, the controller 6 records the feedback values ​​from the temperature and humidity sensor 3 in real time according to a set time, and adds the door status information to the data in its internal memory. This separates the door data for different states, avoids deviations in the temperature and humidity sensor 3's measurements, and ensures the reference value of the temperature and humidity sensor 3's measurements.

[0038] When the temperature and humidity values ​​exceed the set threshold range, or when the cabinet door is not fully closed for a period exceeding the set value, an abnormal situation is identified. When an abnormal situation is detected, the controller 6 controls the alarm device 9 to issue an audible and visual alarm. The controller 6 records information such as alarm time, alarm type, and current temperature and humidity values ​​in its internal memory for later retrieval and analysis.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
