Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments to this utility model it is described in detail.It should be noted that
In the case of not conflicting, the feature in following embodiment and embodiment can be mutually combined.
As it is shown in figure 1, the condensate tank of dehumidifier in one of them embodiment of this utility model includes some metals
Sheet 21 ..., 28, detection chip IC30 and MCU40 (not shown), some sheet metals 21 ...,
28, detection chip IC30 is arranged on circuit board 50.
As shown in Fig. 2 a, 2b, circuit board 50 is arranged on container 10 outside or is loaded on appearance by sealing device
In device 10, some sheet metals 21 ..., 28 arrange along container 10 short transverse with a determining deviation, Ruo Ganjin
Belong to sheet 21 ..., spacing between 28 can be can also to be equidistantly unequal-interval.Institute in the present embodiment
State sheet metal 21 ..., 28 employing copper products are made, it would however also be possible to employ other metal materials, such as ferrum.Some
Described sheet metal 21 ..., 28 one side or the tow sides being arranged at circuit board 50.Because of manufacturing process and
The demand of sensing, sheet metal needs certain area and height, and the distance of adjacent two sheet metals then defines
The accuracy of detection of water level, and sheet metal positive and negative two and the method that arranges effectively overcome this defect and carry
High accuracy of detection.
As shown in Fig. 3 a, 3b, 3c, some described sheet metals 21 ..., 28 line up two row, and in two row
Sheet metal mutually staggers so that the spacing between two sheet metals halves, and can be effectively improved accuracy of detection.
Described sheet metal 21 ..., 28 be shaped as rectangle (as shown in Figure 3 a) or circular (as shown in Figure 3 c).Work as institute
Stating sheet metal 21 ..., 28 when being shaped as rectangle, one end that sheet metal in two row is relative is that taper is (such as figure
Shown in 3b), precision can be improved further.
As shown in Figure 4, the input K00 ... of described detection chip IC30, K07 are described with some respectively
Sheet metal 21 ..., 28 it is connected, the input of the outfan of described detection chip IC30 and described MCU40
It is connected.
The operation principle of the condensate tank of dehumidifier in this utility model embodiment is as follows: the water level in container 10
After line exceeds some sheet metals 21 ..., certain sheet metal in 28, detection chip IC30 detects this metal
The electric potential signal of sheet, and send MCU40, MCU40 to by being converted into the signal of telecommunication after the process of this electric potential signal
The water level in container corresponding to this sheet metal 10 is calculated according to electric potential signal.MCU40 is according to electric potential signal
The water level calculated in now container 10 is prior art, does not repeats them here.
To sum up, the condensate tank of dehumidifier in this utility model embodiment, owing to detection device is without contacting with water,
So can design and flexible arrangement according to body, and can be located at outside water container or design in the water capacity after sealing
Inside device, design and size arrangement to complete machine bring great probability, and assemble simple, assembling
Efficiency is high, additionally, also have that circuit design is simple, detection accurately and reliably, feature applied widely.
Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and
In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that,
For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to
Making some deformation and improvement, these broadly fall into protection domain of the present utility model.
