The smoke extractor is mainly and technically characterized by also comprising the acoustic device, a power amplifier board and an audio jack, wherein, the power amplifier board is arranged inside the top of the casing main body, the acoustic device is arranged inside the control box, the power amplifier board is in signal connection with the control box and the main control panel, the acoustic device is in signal connection with the power amplifier board, the audio jack is positioned on the control box and is in signal connection with the power amplifier board, and the power amplifier board and the main control panel are in electric connection with power supply input wires. The smoke extractor with the digital power amplifier acoustic device has the characteristics that the digital power amplifier acoustic device can be combined with the smoke extractor effectively, the outer space of the smoke extractor is not occupied, the operation of the smoke extractor is not influenced, etc.

Description

The range hood of band digital power amplifier PA-system
Technical field:
The utility model relates to a kind of range hood with the digital power amplifier PA-system.
Background technology:
In background technology, range hood is generally the combination between fast shelves/slow shelves, illumination, the time-delay, if user (housewife etc.) cooks in the kitchen during housework such as cooking, listen beautiful melodious music, need carry special-purpose sound appliances or the sound of the main power amplifier in parlor in the family is strengthened, this all seems not too convenient.For overcoming these defectives, the range hood of band digital power amplifier PA-system is developed.
Summary of the invention:
Technical problem to be solved in the utility model is that a kind of range hood with the digital power amplifier PA-system will be provided, it can incorporate digital power amplifier PA-system system in the range hood effectively, and do not take the space outerpace of range hood, do not influence the operation of range hood.
The technical scheme that its technical problem that solves the utility model adopts is:
It comprises control box, master control borad, power input line, shell main body, it also comprises sound equipment, power board, audio sockets, described power board is installed in going up of shell main body and pushes up inner, sound equipment is installed in control box inside, power board connects with control box and master control borad signal, sound equipment connects with the power board signal, and audio sockets is positioned on the control box and with the power board signal and connects, and power board and master control borad and power input line electrically connect.
The profile and the control box of described sound equipment fit tightly.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model adopts sound equipment, power board, audio sockets and range hood to combine, so it can incorporate digital power amplifier PA-system system in the range hood effectively, and do not take the space outerpace of range hood, do not influence the operation of range hood.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Shown in accompanying drawing 1, in the present embodiment, sound equipment 2 is installed in the inside of control box 1, the profile of sound equipment 2 and control box 1 fit tightly, master control borad 3 and power board 4 are installed in going up of shell main body 6 and push up inner, the holding wire of control box 1 is connected with master control borad 3, the holding wire of master control borad 3 connects with power board 4, the power input line 5 logical 220V power supplys of going up, audio signal at sources of sound such as input MP3 of audio sockets 7 places or MP4, according to display requirement on function key on the control box 1 and the display screen, can set volume respectively, fast shelves/slow shelves, illumination, delay time etc., display screen can show the working condition of corresponding function in turn, does not need to carry extra PA-system, can when the kitchen does housework, can appreciate beautiful music again, enjoy a kind of enjoyment at work.
As long as input MP3, audio signals such as MP4 and CD just can make range hood have functions such as fast shelves/slow shelves, illumination, time-delay, can play melodious music again simultaneously.The digital power amplifier sound system designs the reasonable position at range hood dexterously, does not take the space outerpace in range hood and kitchen, does not influence the operation of range hood, and profile is more attractive in appearance.
Power amplifier acoustic function and range hood function can be used simultaneously, also can use separately, and two functions get in same body, and mutually noninterfere makes simple to operate clear.
