Detailed Description
FIG. 1 is a schematic block diagram of a display device 100 according to one embodiment of the present invention; FIG. 2 is a schematic block diagram of the display device 100 of FIG. 1 viewed from another angle; fig. 3 is a schematic cross-sectional view taken along a vertical central plane of the display device 100 shown in fig. 1. Referring to fig. 1-3, display device 100 may include a humidifying assembly 130 for oscillating and atomizing a humidifying liquid into a gaseous mist, a temperature sensor 140 for sensing a temperature value of a front side environment of display device 100, and a housing for housing humidifying assembly 130 and temperature sensor 140. In particular, the humidifying assembly 130 may be configured to controllably begin operation based on a temperature value sensed by the temperature sensor 140.
The display device 100 of the invention simulates the cold air blown out by the air supply duct of the air-cooled refrigerator 200 through the gaseous water mist generated by the humidifying component 130, and is provided with the temperature sensor 140, so that the humidifying component 130 starts to work in a controlled manner according to the temperature value sensed by the temperature sensor 140, and vividly shows the working principle of the air-cooled refrigerator 200 for conveying the cold air to refrigerate according to whether the cold quantity in the storage room of the refrigerator 200 is sufficient or not.
In some preferred embodiments, the humidifying assembly 130 may be configured to controllably start operating when the difference between two adjacent sensed temperature values of the temperature sensor 140 is greater than or equal to a preset first mutation value; when the difference value between the temperature values sensed by the temperature sensor 140 two adjacent times is smaller than the first mutation value, the operation is not performed. In some embodiments, the temperature sensor 140 may be configured to sense once every 0.1-1 ms, such as 0.1ms, 0.5ms, or 1 ms. The first mutation value may be 0.5 to 2 ℃, for example 0.5 ℃, 1 ℃, 1.5 ℃ or 2 ℃.
In a further preferred embodiment, the humidifying assembly 130 can be configured to controllably adjust its operating power according to the magnitude of the difference between the temperature values sensed by the temperature sensor 140 in two adjacent times. Specifically, when the difference between the temperature values sensed by the temperature sensor 140 at two adjacent times is greater than or equal to the first mutation value and less than a preset second mutation value, the temperature sensor is controlled to operate at a first preset power; when the difference between the temperature values sensed by the temperature sensor 140 at two adjacent times is greater than or equal to the second sudden change value, the temperature sensor is controlled to operate at a second preset power, the second sudden change value is greater than the first sudden change value, and the second preset power is greater than the first preset power. That is, the larger the temperature difference sensed by the temperature sensor 140 is, the higher the operating power of the humidifying assembly 130 is, so as to show the operating principle that the air-cooled refrigerator 200 can adjust the amount of cold air delivered to the storage compartment in a targeted manner according to the amount of cold energy required by the storage compartment of the refrigerator 200. In some embodiments, the humidifying assembly 130 may operate at a power rating of 20-40W, such as 20W, 30W, or 40W. The second mutation value may be 4 to 6 ℃, for example 4 ℃, 5 ℃ or 6 ℃. The second preset power may be a rated power at which the humidifying assembly 130 operates. The first preset power may be 60-80%, for example, 60%, 70% or 80%, of the second preset power, so as to reduce the output of the gaseous water mist on the premise of ensuring that the humidifying assembly 130 can normally generate the gaseous water mist.
