Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is described in further detail with reference to the accompanying drawings and specific embodiments. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.
As shown in fig. 1 to 4, the liquid crystal display device with temperature adjustment function provided in this embodiment mainly includes a frame 1, an air guide plate 2, a heating/cooling unit 3, and a liquid crystal display unit 4. The air guide plate 2 is arranged in the frame 1, the air guide plate 2 is provided with an air channel 21 inside, and the surface of the air guide plate is provided with a plurality of air guide holes 22 communicated with the air channel 21. A heating/cooling unit 3 for generating hot/cold gas is disposed in the frame 1. The liquid crystal display unit 4 is disposed in the frame 1 in front of the air guide plate 2. The hot/cold gas generated by the heating/cooling unit 3 can flow through the gas passage 21 of the gas guide plate 2 and be blown toward the liquid crystal display unit 4 via the gas guide hole 22.
Referring particularly to fig. 3, it will be understood by those skilled in the art that a portion of the gas channel 21 is referred to as an inlet channel (to the left as shown) and another portion is referred to as an outlet channel (to the right as shown). Accordingly, a part of the plurality of air guide holes 21 is used as an air outlet hole and another part is used as an air inlet hole, thereby realizing circulation of hot/cold gas in the gas passage 21 of the air guide plate 2.
The liquid crystal display device with the temperature adjusting function heats or refrigerates the liquid crystal display unit 4 in the form of the combination of the heating/refrigerating unit 3 and the air guide plate 2, coated glass, glue and the like do not need to be attached to the liquid crystal display unit 4, and the liquid crystal display device is high in heating efficiency, large in power adjusting range and simple in process.
Further, the heating/cooling unit 3 includes a heating/cooling compartment 31, a return air pipe 32, and an intake air pipe 33. Heating/refrigeration chamber 31 is arranged in frame 1, air return pipe 32 is connected with air guide plate 2 and the air inlet end of heating/refrigeration chamber 31, and air inlet pipe 33 is connected with air guide plate 2 and the air outlet end of heating/refrigeration chamber 31. In order to accelerate the flow of hot/cold gas, the heating/cooling unit 3 may also comprise a fan 34 arranged on said return air duct 32. Referring particularly to fig. 6, the electrical connections within the heating/cooling compartment 31 are shown.
Further, the gas guiding plate 2 is a frame-shaped structure, the gas channels 21 are distributed along the frame-shaped structure of the gas guiding plate 2, and the gas guiding holes 22 are uniformly distributed on the gas channels 21. The liquid crystal display device with the temperature adjusting function also comprises a heat insulation layer 5 arranged in the frame, and the air guide plate 2 is arranged on the heat insulation layer 5. The liquid crystal display unit 4 is fixedly disposed within the frame 1 and is spaced apart from the thermal insulation layer 5 such that a heating/cooling chamber is formed between the liquid crystal display unit 4 and the thermal insulation layer 5.
Based on the above structure, a heating/cooling chamber is formed between the liquid crystal display unit 4 and the thermal insulation layer 5. The heating/cooling chamber 31 generates hot/cold gas, which enters the gas channel 21 of the gas guide plate 2 through the gas inlet pipe 33 and is blown toward the heating/cooling chamber between the liquid crystal display unit 4 and the gas guide plate 2 through the gas guide hole 22. The temperature of the liquid crystal display unit 4 is raised/lowered by the hot/cold gas. Subsequently, the gas in the heating/cooling chamber enters the gas guide hole 22 again, and returns through the gas passage 21 of the gas guide plate 2 and the gas return pipe 32. Due to the action of the fan 34, the air in the heating/cooling bin 31, the air return pipe 32 and the air inlet pipe 33 circulates in a single direction.

Further, in the present embodiment, the heat insulating layer 5 is double-glazing vacuum glass. Thereby ensuring that the temperature of the heating/cooling chamber formed between the liquid crystal display unit 4 and the thermal insulating layer 5 is not dissipated toward the back side.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
