In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
Fig. 1 shows a specific embodiment of a method for detecting humidity in a washing chamber, which includes:
step S101: controlling a light source generating device 3 in the washing cavity 1 to generate light beams, wherein the wavelength of the light beams is larger than the diameter of the gas particles in the washing cavity 1;
step S103: acquiring the light intensity of scattered light of the light beam;
step S105: and acquiring the humidity of the washing cavity according to the light intensity.
In the above-mentioned washing chamber humidity detecting method, the washing chamber 1 may be used for washing. The light source generating device 3 can be used for generating a light beam, based on the principle of linear propagation of light, the light beam generated by the light source generating device 3 can generate a light band in the washing chamber 1, and when light irradiates on particles in the process of propagation of light, when the wavelength of the light wave of the light band is greater than the diameter of the gas particles in the washing chamber 1, scattering of the light occurs. The intensity of scattered light is different due to different humidity, and the intensity of scattered light is larger when the humidity is larger, so that the humidity of the washing cavity can be acquired by acquiring the intensity of the scattered light of the light beam. Although water can be splashed out when the washing chamber 1 is used for washing, the wavelength of the light beam emitted by the light source generating device 3 in the washing chamber 1 cannot be influenced by the water, so that the acquired light intensity cannot be influenced, the accuracy of the humidity of the washing chamber cannot be influenced, and the accurate humidity of the washing chamber can be acquired.
In this case, it is observed that the light wave in the washing chamber 1 is radiated around the particles, which is scattered light or opalescence. The phenomenon of light scattering is the tyndall effect. Since the intensity of the scattered light increases with the concentration of particles in the washing chamber 1, the greater the concentration of particles, the greater the intensity of the scattered light, and the greater the intensity of the scattered light, the greater the humidity of the washing chamber.
As a modified embodiment, as shown in fig. 2, the washing chamber humidity detecting method further includes:
step S107: displaying the value indicative of the humidity of the washing chamber.
The above-mentioned humidity characterization value of the washing chamber represents a humidity range corresponding to the humidity of the washing chamber, so that the humidity condition in the washing chamber 1 can be intuitively understood.
Specifically, as shown in fig. 3, the light source generating device 3 for controlling the washing chamber 1 to generate the light beam specifically includes:
step S201: acquiring a control instruction;
step S203: starting the light source generating device 3 to generate light beams according to the control instruction;
step S205: the light source generating device 3 is adjusted to emit light beams with the wavelength larger than the diameter of the gas particles in the washing chamber 1.
The above-mentioned control command may be input from the outside or triggered synchronously with other related controls, so that the light source generating device 3 can generate the light beam, and then the wavelength of the light emitted from the light source generating device 3 is adjusted to be larger than the diameter of the gas particles in the washing chamber 1, so as to scatter the light beam in the washing chamber 1.
Example 2
Referring to fig. 4, an embodiment of a washing apparatus is shown, and in conjunction with fig. 4, the washing apparatus 10 includes: the method comprises the following steps: the washing device comprises a washing cavity 1, a light source generating device 3, a light detecting device 4 and a control device 2, wherein the light source generating device 3 is arranged in the washing cavity 1, the light source generating device 3 is configured to emit light beams, the light detecting device 4 is arranged in the washing cavity 1, the light detecting device 4 is configured to detect and send the light intensity of the light beams emitted by the light source generating device 3, the control device 2 is in communication connection with the light source generating device 3, the control device 2 is configured to control the wavelength of the light beams emitted by the light source generating device 3 to be larger than the diameter of gas particles in the washing cavity 1 and obtain the light intensity sent by the light detecting device 4, and the control device 2 obtains the humidity of the washing cavity according to the light intensity.
In the above-described washing apparatus 10, the light source generating device 3 and the light detecting device 4 are both disposed in the washing chamber 1, and the light detecting device 4 is used for detecting the intensity of scattered light of the light beam generated by the light source generating device 3 and outputting the detected light intensity. The light detection device 4 transmits the detected light intensity data to the control device 2, and the control device 2 processes the light intensity data to obtain the humidity of the washing chamber. Based on the principle of linear light propagation, the light beam generated by the light source generating device 3 will generate a light beam band in the washing chamber 1, and a light detecting device 4 can be disposed at the end of the light beam band, so that the light detecting device 4 can detect the light beam and obtain the light intensity of the scattered light. Although water also splashes onto the light detection device 4 when washing is carried out in the washing chamber 1, the light detection device 4 is not affected by the splashed water when detecting the light intensity of the light beam in the washing chamber 1, and therefore the obtained light intensity is not affected, and the accuracy of the humidity of the washing chamber is not affected, so that more accurate humidity of the washing chamber can be obtained.
The light source generating device 3 comprises an LED fiber optic machine and the light detecting device 4 comprises an ambient light sensor. The ambient light sensor can sense the ambient light intensity and output the ambient light intensity through an I2C interface. The I2C interface can directly output light intensity, does not need calibration, and is not easy to be interfered by noise. The environment light sensor is internally provided with the infrared photosensitive diode, so that the measurement can be more accurate even in an environment with large infrared noise interference.

The first mounting surface 11 and the second mounting surface 12 may be inner walls of the washing chamber 1, respectively, and the first mounting surface 11 and the second mounting surface 12 form an included angle, which is not 180 degrees, so that the light detection device 4 can detect the intensity of the scattered light of the light beam generated by the light source generation device 3. If the first mounting surface 11 and the second mounting surface 12 are parallel to each other, for example, the light detection device 4 is mounted opposite to the light source generation device 3, the light detection device 4 will continuously receive the light beam generated by the light source generation device 3, and the light beam particles directly strike the detection device, so that the light intensity cannot be identified.
More specifically, as shown in fig. 6, the first mounting surface 11 and the second mounting surface 12 are perpendicular to each other, so that the light detection device 4 can detect and acquire light intensity from the direction of the perpendicular incident light.
The washing chamber 1 may include four inner walls, the first mounting surface 11 is adjacent to the second mounting surface 12, and the light detection device 4 is disposed at the end of the light beam generated by the light source generation device 3, so that the detected data is more accurate.
More specifically, continuing to refer to fig. 6, the light source generating device 3 has a light beam outlet, the light detecting device 4 has a detecting port, and the center of the light beam outlet and the center of the detecting port are located on the same horizontal plane, so that the light detecting device 4 is not too far away from the end of the light beam, the photosensitive element arranged inside the light detecting device 4 can be prevented from exceeding the detecting range, the photosensitive element of the light detecting device 4 is in the detecting range, and therefore, the intensity of the scattered light detected by being installed on the same horizontal plane is more accurate.
The washing device 10 further includes: and the display device 5 is in communication connection with the control device 2, and the display device 5 is configured to display the value representing the humidity of the washing cavity. The humidity of the washing chamber can be obtained more intuitively by displaying the humidity of the washing chamber through the display device 5.

The spray arm is disposed in the washing chamber 1 of the dishwasher 100, and the spray arm sprays water while rotating to clean the dishes in the washing chamber 1 of the dishwasher. Because the light detection device 4 and the light source generation device 3 of the washing device can not be influenced by the water sprayed in the washing process, the detection of the humidity of the washing cavity of the dish washing machine is more accurate, the dish washing machine can be ensured to have a better drying effect, and the reliability of the performance of the dish washing machine is improved.
The dishwasher 100 mainly includes a control device 2, a light source generating device 3, a light detecting device 4, and a display device 5. The control device 2 mainly controls the light source generating device 3 to generate light sources; the light source generating device 3 can emit light beams with different wavelengths and energies, the light detection device 4 can detect the light beam radiation which is not absorbed by the gas in the inner cavity of the dishwasher, namely the intensity of the light beams, and the display device 5 is used for displaying the value of the humidity in the inner cavity of the dishwasher for a user. The light source generating device 3 is mounted on one of the four lateral surfaces of the washing chamber 1 of the dishwasher, the light detecting device 4 is mounted on the other of the four lateral surfaces, and the mounting plane of the light detecting device 4 is perpendicular to the mounting plane of the light source generating device 3. The detection device and the light source generating device 3 should be on the same horizontal plane, and the light detection device 4 should be installed at one end far from the installation plane of the light source generating device 3. As shown in FIG. 6, the control device 2 controls the light source generating device 3 to emit a light beam to irradiate the gas in the inner chamber of the dishwasher. The control device 2 is adjusted to make the light source generating device 3 generate light beams with wavelengths larger than the diameters of the gas particles, and then light scattering occurs when the light beams irradiate the gas particles in the light propagation process, and at this time, if the light waves surround the gas particles and radiate to the periphery of the gas particles, which is observed by naked eyes, the phenomenon is called scattered light or opalescence, and the phenomenon of light scattering is called opalescence, namely the tyndall effect. The intensity of scattered light is enhanced along with the increase of the concentration of gas particles, the light detection device 4 detects the intensity of the scattered light from the direction of vertical incident light at the tail end of a light beam, and further the magnitude of the gas humidity in the inner cavity of the dishwasher is indirectly known in the display device 5, and the greater the detected intensity of the scattered light, the greater the humidity in the inner cavity of the dishwasher.
Compared with the method for acquiring the humidity data of the washing cavity of the dishwasher by using the humidity sensor, the dishwasher 100 has the advantages that the humidity sensor is easily wetted by water to influence the acquisition of the humidity data of the washing cavity, the dishwasher irradiates the gas in the inner cavity of the washing cavity 1 of the dishwasher by using the light source generated by the light source generating device 3, so that a bright 'channel' is formed in the gas-filled inner cavity, then the intensity of the light beam is detected from the direction of the vertical incident light at the tail end of the 'channel' by the light detecting device 4, and the humidity of the gas in the inner cavity of the dishwasher is represented by the intensity of the light beam.
