Abstract
The utility model relates to a work status indicator for air conditioners which can rationally indicate the work status of air conditioners. The prior component which can indicate the work status of air conditioners is rare. The utility model is characterized in that the utility model consists of a digital indicator which is arranged on the indoor framework of the air conditioner. The digital indicator is connected with a control circuit, while the control circuit is connected with a sensor. The digital indicator takes a digital indicating tube which consists of a luminescence crystal diode. The utility model is used for rationally indicating work statuses such as temperature and moisture for air conditioners.
Description
(1) technical field:
The utility model belongs to the display unit of air-conditioner duty.
(2) background technology:
The display unit of existing air-conditioner duty is to show by single lighting transistor, by being installed on the lighting transistor that can send different colours such as red, green on the indoor set frame plate, shows refrigeration, heats, duty such as defrosting.The shortcoming of this display unit is can only qualitative display working condition, and quantitative display working condition for example can't show refrigeration or heat the temperature value of state; Secondly, the device of display working condition is many, and a kind of duty will show with a lighting transistor.
(3) summary of the invention:
The purpose of this utility model is to provide the display unit of another kind of air-conditioner duty, and it can quantitatively show the duty of air-conditioner, and the device of display working condition is few.
Of the present utility modelly be characterised in that it is made of the digital display device that is installed on the air conditioner room unit frame plate, said digital display device is connected with control circuit, and control circuit is connected with sensor in addition.Said digital display device is the digital display tube that is made of lighting transistor.
When air-conditioner is in running order, when for example being in refrigeration or heating state, temperature sensor perception indoor temperature, the temperature signal of sensor passes through control circuit, on light-emitting nixie tube, demonstrate the indoor temperature value, so reach the technique effect that can quantitatively show the air-conditioner duty.If on control circuit, connect humidity sensor, quantitative humidity value in the display room again on same light-emitting nixie tube so.Equally, if on control circuit, connect the other types senser element, also can on same light-emitting nixie tube, show other duties.Therefore, the utility model can show the multiple duty of air-conditioner by a digital display device, and the device of display working condition is few.
(4) description of drawings:
Fig. 1 is air conditioner room unit and front view of the present utility model:
Fig. 2 is a partial elevational enlarged drawing of the present utility model
(5) the concrete mode of Shi Shiing:
See Fig. 1, being constructed as follows of air conditioner room unit casing has framework 2 in it, and device panel 1,3 is the Main subrack frame plate of framework 2 on the framework 2, and the utility model promptly is made of the digital display device 4 that is installed on the Main subrack frame plate 3.5 for being installed on the decorative panel of the translucent plastic material on the Main subrack frame plate.Fig. 2 is the partial enlarged drawing at the utility model display unit 4 and Main subrack frame plate 3 positions, and other the part coding among the figure is same as shown in Figure 1.
See Fig. 1, Fig. 2, digital display device 4 can be liquid crystal display device or charactron display device etc., but the best is the luminous digital display tube that is made of lighting transistor, as the luminous digital display tube of luminescent crystal diode formation.Typical marque such as NED-4022AG, Ai Mida electronics corporation in Ningbo makes; Connected control integrated circuit marque such as T4LS164, TIX makes; The temperature sensor model that is connected with control circuit, as R4=5K/B3470, Japanese stoneman Co., Ltd. makes; The model of humidity sensor, as RHU-222, Japanese Dragon Lord Co., Ltd. makes.Above-mentioned control circuit chip is connected by prior art with the method for attachment of said luminescent crystal diode and senser element.Wherein control circuit generally all uses IC chip, is installed on the circuit board within the indoor set casing, and sensor device is in the position of a certain duty of energy perception air-conditioner.
Claims (2)
1. the display unit of air-conditioner duty is characterized in that it is made of the digital display device that is installed on the air conditioner room unit frame plate, and said digital display device is connected with control circuit, and control circuit is connected with sensor in addition.
2. by the display unit of the said duty of claim 1, it is characterized in that said digital display device is the digital display tube that is made of lighting transistor.
