Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, and in particular to a large-screen external thermostat. Background Technology

[0002] With social development and the continuous improvement of people's living standards, people's requirements for the comfort of indoor appliances are also increasing. As a popular household appliance, the temperature control accuracy of the air conditioner's temperature control panel has become an important factor in improving user comfort. Air conditioner thermostats are widely used in temperature control in smart hotels, homes, commercial spaces, and industrial areas. Through program control, they send various signals to actuators such as air conditioners, fans, and electric valves, responding to user operations and settings to achieve functions such as heating, cooling, ventilation, and purging, creating a comfortable environment.

[0003] Traditional air conditioner thermostats can be categorized by control method into electronic and mechanical types, and by display into LCD and adjustable types. However, existing LCD air conditioner thermostat panels typically have the LCD display set up in a separate area (e.g., Figure 1 As shown, its front wall is divided into several areas, one of which houses the LCD screen 1; the other areas are used to house the button aluminum plate 2, the mode indicator panel 3, and the temperature control panel housing 5. However, this design makes the air conditioner temperature control panel structure not compact and lacks a simple and aesthetically pleasing operating interface. In addition, the temperature probe of most traditional thermostats is usually located in the thermostat body, which leads to a certain error when the temperature probe, controller, and display panel display the indoor ambient temperature. This results in a discrepancy between the user's actual perceived temperature and the actual temperature displayed by the thermostat. Utility Model Content

Obviously, the described embodiments are some, but not all, embodiments of this utility model. 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.

[0032] The preferred embodiment of this utility model is a large-screen external temperature controller, such as... Figure 2-7 As shown, the system includes a front shell module 10, a temperature control switch control board 20 disposed within the front shell module 10, a rear shell module 30 detachably disposed on the rear side wall of the front shell module 10, and a power control board 40 disposed within the rear shell module. The front side wall of the temperature control switch control board 20 is completely covered by a display screen 50. The lower end of the temperature control switch control board 20 has an extension 21, on which touch buttons 60 are integrated. A temperature probe 70 is disposed at the lower end of the extension 21. The front end of the front shell module 10 has a screen display window 80, a touch window 90, and a probe temperature sensing window 100 corresponding to the display screen 50, the operation buttons, and the temperature probe 70, respectively. The front sidewall of module 10 is provided with a light-transmitting panel 110 that covers the screen display window 80 and the touch window 90. The front shell module 10, the temperature control switch control board 20, the power control board 40, and the display screen 50 are all square structures. The light-transmitting panel 110 completely covers the touch area and the display area, and ensures that the display area is much larger than the touch area, making the product visually closer to a full-screen display, without losing normal touch operation functions. In addition, the temperature probe 70 is installed at the bottom of the shell through the extension 21 and exposed to the outside, which can significantly reduce the deviation between the system's feedback temperature and the actual temperature, and ensure the accuracy of actual control.

[0033] In this embodiment, multiple touch buttons 60 are arranged in a straight line below the display screen 50, and the vertical width of the arrangement is less than or equal to one-third of the vertical width of the display screen 50, so as to ensure the overall screen ratio of the display screen 50 and the integrity of the product. The screen display window 80 and the touch window 90 are both located on the front side wall of the front shell module 10, and the temperature sensing window 100 is located on the lower end surface of the front shell module 10. This layout design allows the temperature probe 70 to be away from the screen, which is a heat source, so as to further reduce the deviation between the system's feedback temperature and the actual temperature. Moreover, placing the temperature probe 70 at the lower end can also achieve the purpose of hiding the design, which relatively improves the overall appearance and neatness of the product after installation.

[0034] In this embodiment, the front shell module 10 includes a square front shell panel 101, a screen display window 80, a touch window 90, and a light-transmitting panel 110, all of which are disposed on the front shell panel 101. The rear side wall of the front shell panel 101 has a first receiving groove 1a for accommodating the temperature control switch control board 20, and the shape of the first receiving groove 1a is also square. Furthermore, the front shell module 10 also includes a front shell bottom plate 102 that covers the temperature control switch control board 20 on the bottom surface of the first receiving groove 1a. After assembly, the outer peripheral side wall of the front shell bottom plate 102 is in contact with the inner side wall of the first receiving groove 1a. A second receiving groove 1b is provided on the front side wall of the front shell bottom plate 102 corresponding to the temperature control switch control board 20. Specifically, the second receiving groove 1b is also square. The first receiving groove 1a and the second receiving groove 1b enclose a front mounting cavity for mounting the temperature control switch control board 20, the display screen 50, and the extension 21. The probe temperature sensing window 100 is located on the lower end surface of the front mounting cavity. Specifically, the lower end side walls of the first receiving groove 1a and the second receiving groove 1b each have a notch 1c to avoid the temperature probe 70. The two notches 1c enclose a probe temperature sensing window 100 to avoid the temperature probe 70.

[0035] In this embodiment, a first protruding buckle 120 is provided on the rear side wall of the front shell panel 101 at the edge of the first receiving groove 1a. There are multiple first protruding buckles 120, and two are arranged side by side on each side of the first receiving groove 1a. The bottom surface of the second receiving groove 1b is provided with a first slot 130 that is adapted to the first protruding buckle 120. The first slot 130 corresponds to multiple first protruding buckles 120 and is provided one-to-one. Through the cooperation of the first protruding buckle 120 and the first slot 130, the convenience of assembly and disassembly can be significantly improved.

[0036] The first protruding buckle 120 is flush with the inner wall of the first receiving groove 1a. When assembled, the side walls of the display screen 50 and the temperature control switch control board 20 abut against the first protruding buckle 120 to achieve elastic positioning.

[0037] In this embodiment, the bottom surface of the second receiving groove 1b has a first recessed portion 1b1 that is recessed to the rear.

Furthermore, the bottom surface of the clearance groove has a first through hole b10 for the first control interface 201 on the temperature control switch control board 20 to pass through, so as to connect with the second control interface 401 on the front side wall of the power control board 40. Through the two first control interfaces, the front shell module 10 and the rear shell module 30 can be formed into two modules that can be quickly separated. While ensuring that the integration can achieve normal functions, it is also convenient to replace or repair the front and rear modules separately in the later stage.

[0038] In this embodiment, the rear shell module 30 has a second recess 3a adapted to the first recess 1b1. The inner sidewall of the second recess 3a has a second protruding buckle 140, and the outer sidewall of the first recess 1b1 has a second slot 150 adapted to the second protruding buckle 140. The bottom surface of the inner cavity of the second recess 3a has a second through hole a1 corresponding to the first through hole b10.

The front panel 301 of the rear shell has a frame plate 303 on the rear side; the front panel 301 of the rear shell and the frame plate 303 are detachably connected; the second recess 3a is located in the center of the front side wall of the front panel 301 of the rear shell, and the frame plate 303 has a third through hole 160 for the second recess 3a to pass through rearward; through the snap-fit ​​connection of the first recess 1b1 and the second recess 3a, quick assembly and disassembly can be achieved, and the connection structure can be avoided from being directly set on the rear side wall of the bottom plate 102 of the front shell to affect the fit with the frame plate 303, which can effectively prevent the overall volume of the thermostat from increasing further and ensure the compactness of the front and rear modules after assembly.

[0039] In this embodiment, the front side wall of the frame plate 303 is provided with a third receiving groove 3b for accommodating the front panel 301 of the rear shell, and a third through hole 160 is provided on the bottom surface of the third receiving groove 3b. The front panel 301 of the rear shell can be directly hidden and installed through the third receiving groove 3b. The frame plate 303 and the front panel 301 of the rear shell are connected by screws 170 to facilitate synchronous connection. In actual installation, the thermostat can be directly fixed to the external mounting base using the screws.

[0040] Furthermore, the outer diameter of the frame plate 303 is the same as the outer diameter of the front shell panel 101, and the outer diameter of the front shell bottom plate 102 is the same as the inner diameter of the third receiving groove 3b. When assembled, the front side wall of the frame plate 303 is attached to the rear side wall of the front shell panel 101 and the front shell bottom plate 102 is encapsulated inside the third receiving groove 3b.

[0041] In this embodiment, the front end of the rear cover 302 has a third protruding buckle 180, and the bottom surface of the second recess 3a is provided with a third slot 190 that is adapted to the third protruding buckle 180. Specifically, there are multiple third protruding buckles 180 that are evenly distributed on the front end surface of the rear cover 302. The modular assembly design of the rear cover module can be realized through the cooperation of the third protruding buckle 180 and the third slot 190, which not only facilitates the separate processing and manufacturing in the early stage, but also facilitates the individual replacement or disassembly and maintenance in the later stage.

[0042] Furthermore, the side wall of the rear cover 302 has a wiring port 200 corresponding to the wiring terminals on the power control board, so as to provide a slot for connecting cables of external power supply.

[0043] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
