A temperature indicating device for an air conditioner

Abstract

The invention discloses a temperature indicating device for an air conditioner. The temperature indicating device is used for displaying a plurality of LED (Light Emitting Diode) lamp temperature parameters on a substrate and comprises a lamp plate seat and a lamp plate which is vertically arranged on the lamp plate, wherein the lamp plate is a transparent piece; a plurality of rows of concave oblique planes which can change the optical propagation path are arranged on the lamp plate; the dip angles of the concave oblique planes are 45 degrees; the concave oblique planes are frosting surfaces; light rays emitted by each LED lamp are reflected through the 45-degree concave oblique planes and are subjected to transmission by the lamp plate; the propagation path of the light rays is rotated for 90 degrees. The device also comprises a substrate lower cover, a substrate upper cover and a light guide plate, wherein the substrate upper cover is assembled on the substrate lower cover; the light guide plate is arranged on the substrate upper cover and is located on the bottom end of the lamp plate; the light rays emitted by the LED lamps on the substrate are subjected to transmission from the light guide plate and the lamp plate and are subjected to transmission by the lamp plate. According to the device, the internal horizontal mounting space in the air conditioner is saved, the refraction of the light rays in the air medium is effectively eradicated, the light diffusing capability is improved, the capability of preventing water immersion is improved, the appearance design is novel, and the third dimension is strong.

Description

Technical field [0001] The present invention relates to the field of air conditioner display, in particular to a temperature display device for air conditioners. Background technique [0002] The Chinese patent document No. 00022514.9 discloses a light-mask backlight type temperature control display for refrigeration and air conditioning. The light emitted by the light emitting diode of the temperature control display needs to be refracted in the air several times and finally reaches the LCD panel, which affects the lighting effect. At present, the temperature indicating device used in air conditioners generally adopts a horizontally superimposed structure, such as Image 6 As shown, the light source 1'is arranged behind the display panel 2', refracts to the display panel 2', and adopts a laterally superimposed structure, which requires space in the horizontal direction of the structure, and cannot be assembled in a narrow space. And the design is not novel enough. [0003] The li...

Problems solved by technology

[0002] The Chinese Patent No. 00242514.9 discloses a photomask-backlit temperature control display for refrigerated air conditioners. The light emitted by the light-emitting diode of the temperature control display needs to go through several refractions in the air and finally reach the liquid crystal display panel, which affects the lighting. Effect

At present, the temperature display devices used in air conditioners generally adopt a horizontally stacked structure, such as Image 6 As shown, the light source 1' is set behind the display panel 2', refracted to the display panel 2', and adopts a horizontally stacked structure, which requires space for the horizontal assembly of the structure, and cannot be assembled in a narrow space. And the appearance design is not novel enough

[0003] Because the light source 1', substrate 3', and wiring harness 4' are all arranged behind the display panel 2' in a common display device, the display panel 2' cannot be made completely transparent, otherwise the structural parts inside will be like the exterior parts Displayed in front of customers, affecting appearance

[0004] The non-transparent display panel also needs to solve the problem of light transmittance. The brightness of LED lights is refracted through the colored display panel, which will reduce the light transmittance and cannot achieve the brightness effect of refraction through transparent materials.
