Detailed Description
Example one
As shown in figure 1, the water inlet box with the function of detecting whether the detergent is put in comprises a box body and a detection electrode, wherein the detection electrode is arranged in the box body, and the detection electrode is arranged at the bottom of an inner cavity of the box body.
The detection electrodes are installed in pairs, the detection electrodes are horizontally placed in the box body and are kept parallel relatively, the detection electrodes are connected with the detection circuit, pulse voltage is input to the input end of the detection circuit, whether detergent exists in the box body or not is judged according to the output value of the output end of the detection circuit, the output end of the detection circuit is connected with the washing machine information processing device, and the washing machine information processing device is electrically connected with the washing machine prompting device. The detection circuit is shown in fig. 4.
Because of the output value of the output end of the detection circuit and the relation between the output value and the conductivity between the two detection electrodes, the conductivity between the two detection electrodes can be known according to the output value of the output end of the detection circuit, and when the mediums between the two detection electrodes are different, the conductivity between the two detection electrodes is different, so that whether the detergent exists in the box body or not can be known according to the output value of the output end of the detection circuit.
In order to ensure that the difference of the conductivity can be obviously reflected, the two detection electrodes need to be kept in parallel, the difference of the reaction conductivity can be most obviously reflected between the distances of 2mm and 10mm, the difference of the reaction is gradually weakened when the distance is more than 10mm, and in order to avoid the water film forming between the two detection electrodes, the distance between the two detection electrodes is preferably 8-10 mm.
In order to ensure that the difference of the conductivity can be obviously reflected, the effective length of the detection electrode is more than 4mm, and the effective length refers to the opposite length of a pair of detection electrodes which can be simultaneously contacted with water or detergent. In order to ensure that the detection electrode can also ensure an effective length with less washing liquid, the detection electrode preferably has a length of more than 10 mm.
In order to ensure that the difference of the conductivity can be obviously reflected, the detection electrode is made of metal and has certain rust resistance and corrosion resistance. A stainless steel electrode may be used from the viewpoint of cost, a titanium-plated ruthenium oxide electrode may be used from the viewpoint of corrosion resistance, or a platinum-plated titanium electrode is more preferable from the viewpoint of corrosion resistance and high sensitivity. In this example, a platinum-plated titanium electrode was selected.
In this embodiment, as shown in fig. 1, the detection electrode is installed at the bottom of the inner cavity of the water inlet box, the detection electrode is shaped as L, so that one end of the detection electrode can extend to the lower side of the bottom plate of the water inlet box and is connected with the information processing device of the washing machine through a wire.
In other embodiments, as shown in FIG. 2, the detection electrode is fixed to the bottom plate of the inlet box by a grid fixture on the bottom plate of the inlet box inner end, which reduces the blocking effect of the fixture on the detergent.
In another embodiment, as shown in fig. 3, the water inlet box is divided into two parts, one is a semi-open fixing member fixed in the washing machine, and the other is an inner end-open drawer, the drawer can be drawn out to place the detergent in the drawer, the two parts are matched with each other, the drawer can be drawn out from or pushed into the fixing member, a pair of detection electrodes is fixed above the bottom plate of the fixing member, and a gap is formed between the detection electrodes and the bottom plate of the fixing member. The detection electrode is fixed on the fixing piece through a grid-shaped fixing device, so that the blocking effect of the fixing device on the detergent is reduced. After the drawer is pushed into the fixing piece, the bottom plate of the drawer is inserted between the detection electrode and the bottom plate of the fixing piece, the distance between the detection electrode and the bottom plate of the drawer meets the detection requirement, and the distance between the detection electrode and the bottom plate of the drawer cannot be too large so that the detection electrode cannot detect the detergent when the detergent is less.
Because of different components of the detergent, different liquids exist between the two detection electrodes, different conditions for forming the water film by different liquids are different, the distance between the two detection electrodes required for forming the water film between the two detection electrodes by some liquids is small, and the distance between the two detection electrodes required for forming the water film between the two detection electrodes by some liquids is large. In order to avoid forming a water film between the two detection electrodes to influence the detection result, in other embodiments, the distance between the two detection electrodes can be adjusted, the driving device is connected with the detection electrodes and can adjust the distance between the two detection electrodes, the driving device is installed in the water inlet box body and is electrically connected with the washing machine information processing device, and the washing machine information processing device sends a command to enable the driving device to act according to different detergents put in the water inlet box so as to adjust the distance between the two detection electrodes to avoid forming the water film between the two detection electrodes. It will be appreciated that experimental data of the spacing of the two detection electrodes required for their formation of the water film for different detergents has been stored in the washing machine information processing device, and such data information can be enriched by the user by downloading updates.
The difference of the conductivity is used for distinguishing whether detergent is put into the water dividing box or not or whether water is fed into the water dividing box or not. At the time point needing to be detected, the input end of the detection circuit provides a rated voltage value, and the output end of the detection circuit outputs a corresponding output value. The output value is related to the conductivity between two ends of the detection electrode, and because the difference between the conductivities of tap water and detergent is large, the output value is obviously different when the tap water is between the detection electrodes and the detergent is between the detection electrodes, and whether the detergent exists in the water inlet box or not is judged through the output value. It will be appreciated that the relationship between the conductivity and the input value at the input of the detection circuit and the output value at the output of the detection circuit has been known experimentally and experimental data has been stored in the washing machine information processing device, and that such data information can be enriched by the user by downloading updates.
When the washing machine has no fault, after the washing program is started to be executed, the washing machine information processing device controls the power supply to input pulse voltage at the input end of the detection circuit and processes the output value at the output end of the detection circuit. By the water inlet box with the function of detecting whether the detergent is put in, the following four conditions in the water inlet box of the washing machine can be distinguished: 1. no water, no detergent; 2. no detergent and water; 3. the detergent is contained and the water is not contained; 4. the detergent and the water are contained. When the washing machine has no fault, the following information can be fed back to the user through the prompting device by the detection after the washing program is started to be executed: 1. no detergent is added and no tap is boiled; 2. no detergent is added; 3. the detergent and the tap without boiling water are thrown; 4. no hint is given. In this embodiment, the prompting device includes a display interface of the washing machine and an alarm device.
