Description

Technical Field

[0001] The utility model relates to the technical field of material drying rooms, in particular to the control technology of drying rooms. Background Art

[0002] Compared with electric heating, heat pumps are more energy-efficient. With the development of the Internet of Things and the large-scale application of heat pump drying, more and more users are beginning to use heat pump drying systems to dry materials.

[0003] The existing heat pump drying room (baking room) includes a drying room, a heating room and a heat pump system. The heat pump system includes a compressor, a condenser, a throttling device and an evaporator connected by a refrigerant pipeline. The condenser is arranged in the heating room; the compressor can be arranged in the heating room together with the condenser, or it can be combined with the throttling device and the evaporator to form a heat pump host; the heat pump host can be arranged in a separate host room, or it can be arranged on the ground outside the drying room;

[0004] A drying rack is provided in the drying room, and a circulating fan is provided between the condenser and the drying room. The circulating fan is used to form a circulating air that continuously flows through the drying room and the condenser. The circulating air absorbs the heat of the condenser and heats the materials on the drying rack in the drying room. A temperature sensor is provided in the drying room, and an electric control device (which can be installed in a control cabinet) is provided on one side of the heating room. The electric control device is used to control the heat pump system and the circulating fan. The electric control device is connected to the temperature sensor, the controller of the heat pump system (called the heat pump controller) and the controller of the circulating fan (called the fan controller); the electric control device is connected to a touch screen, and the user monitors the working status of the heat pump drying room through the touch screen, and adjusts the drying parameters of the heat pump drying room (such as the predetermined drying temperature). Among them, the electric control device adopts a single-chip microcomputer, such as a 51 single-chip microcomputer or a PLC.

[0005] The existing electric control device is arranged in a control cabinet, and the control cabinet is arranged on the side wall of the heating chamber or in the heating chamber. The touch screen is exposed outside the heating chamber and is connected to the electric control device through a wired line. The operation mode is generally standing operation.

[0006] The touch screen is located outside the drying room. Users sometimes need to observe the operating status of the drying room or adjust baking parameters at the control cabinet in the rain or under the scorching sun.

[0007] Drying rooms are usually built outside the city, which makes it easier to operate and transport materials before and after drying. The lighting conditions outside the city are usually poor at night. At night, drying room users still need to use flashlights, headlamps and other lighting equipment to check the equipment status and adjust the baking parameters, which is inconvenient to use at night.

[0008] In pursuit of low costs, some drying room manufacturers on the market have applied a large number of low-cost touch screens, whose viewing angles and brightness are not ideal, causing great inconvenience and trouble for users to view equipment status information and adjust and modify drying parameters.

[0009] In addition, the baking parameters used by users when baking certain materials are extremely important, and involve the technical secrets of the drying effect. The touch screen of the control cabinet is set on the outer wall of the drying room, and others may come to use random passwords to try to log in and obtain technical secrets. In order to prevent others from viewing and modifying parameters, users need to set multiple passwords. Over time, users may make mistakes in passwords or forget them, and need to contact after-sales service to resolve.

[0010] In summary, the existing setting position (on the outer wall of the drying room) and connection relationship (connected to the electronic control device of the heat pump system in the control cabinet through a wired line) of the touch screen used to check the drying room status and adjust the drying parameters have brought about the above-mentioned problems. Utility Model Content

[0011] The utility model aims to provide a heat pump drying system with a quick-detachable mobile operating screen, wherein the touch screen (ie, the operating screen) can be removed from the outer wall of a drying room for use.

[0012] To achieve the above-mentioned purpose, the heat pump drying system with a quick-detachable mobile operating screen of the utility model comprises a drying chamber, a heating chamber and a heat pump system, the heat pump system comprises a compressor, a condenser, a throttling device and an evaporator connected in a refrigerant pipeline cycle, and the condenser is arranged in the heating chamber;

[0013] A drying rack is provided in the drying room, a circulating fan is provided between the condenser and the drying room, the circulating fan is used to form circulating air that continuously flows through the drying room and the condenser, a temperature sensor is provided in the drying room, a fixed electric control device is provided on one side of the heating room, the fixed electric control device is used to control the heat pump system and the circulating fan, and the fixed electric control device is connected to the temperature sensor, the controller of the heat pump system and the controller of the circulating fan; a touch screen is also included, the touch screen has a built-in mobile electric control device, and the user monitors the working status of the heat pump drying room through the touch screen and adjusts the drying parameters of the heat pump drying room;

[0014] The fixed electric control device is connected to a first wireless communication module, and the mobile electric control device is connected to a second wireless communication module. The fixed electric control device and the mobile electric control device are connected to each other by wireless communication via the first wireless communication module and the second wireless communication module; the mobile electric control device is connected to a storage battery.

[0015] The fixed electric control device is installed on the side wall of the heating chamber, and the side wall of the heating chamber is also provided with a screen embedding groove for temporarily fixing the touch screen.

[0016] The utility model has the following advantages:

[0017] By adopting the structure of the utility model, the touch screen and its electric control device (mobile electric control device) are freed from the constraints of wired connection, and the staff can carry the touch screen to a suitable place to check the state of the drying room or adjust the drying parameters. On rainy days, when the sun is scorching, or at night, the touch screen can be carried indoors for operation; when there is a risk of people watching, it can be carried to a place away from people for operation; when the staff leaves the drying room, the touch screen can be taken away to eliminate the risk of leakage of passwords by others. In short, by adopting the utility model, it is convenient for the staff to carry out the monitoring work and parameter adjustment work of the drying room more comfortably and safely, and the risk of leakage can be eliminated.

[0018] When the safety of the drying system (drying room) is guaranteed (such as the drying room is located in the user's factory or farm), the operator can embed the touch screen into the screen groove. When using it, it can be operated at the screen on the outer wall like the existing drying room, or the touch screen can be removed and operated. The operator does not need to carry the touch screen with him all the time, which is convenient for the operator. BRIEF DESCRIPTION OF THE DRAWINGS
