In this embodiment, the dishwasher may be an embedded dishwasher, a sink dishwasher or a desk dishwasher, wherein the water cup 7 and the washing pump 5 are commonly used components of the dishwasher, and will not be described herein.
As shown in fig. 1, two sensor modules 8 are installed on the side wall of the water cup 7 and the pipe 6 respectively. Through installing two sensor module 8 on drinking cup 7 lateral wall and pipeline 6, can avoid causing dish washer work abnormality because of one of them sensor module 8 trouble to enable data detection more accurate, thereby guarantee dish washer's work accuracy.
The sensor module 8 in this embodiment comprises a housing, a first sensor body, a circuit board (not shown in the figures) and at least one second sensor body 4. The shell comprises a main body part 11, and a first extension part 12 and a second extension part 13 which are convexly arranged on the upper surface of the main body part 11 and are oppositely arranged at intervals, the first extension part 12 and the second extension part 13 are hollow and made of light-transmitting materials, and the first extension part 12 and the second extension part 13 penetrate through the upper surface of the main body part 11; as shown in fig. 4, the cross sections of the first extension portion 12 and the second extension portion 13 are in the same semicircular shape, and the arc portions of the first extension portion 12 and the second extension portion 13 are outward; the first sensor body comprises a light emitting unit 21 arranged in the first extension part 12 and a light receiving unit 22 arranged in the second extension part 13, and is used for detecting turbidity of water discharged by the dish washer; in this embodiment, the first sensor body is a turbidity sensor, and correspondingly, the light emitting unit 21 is an infrared emitting tube, and the light receiving unit 22 is an infrared receiving tube; the circuit board is disposed in the main body 11 and is connected with the first sensor body and the second sensor body 4, and the second sensor body 4 may be a sensor with different types or a sensor with the same type, and the specific type of the second sensor body 4 may be adaptively changed according to actual needs, for example: water level sensors, water pressure sensors, etc. Of course, the above-mentioned sensor module 8 further includes a cover 9 fixedly mounted to the main body 11, and a buckle or a slot for detachably mounting the sensor module 8 is provided on the cover 9, which can be made by a person skilled in the art, and will not be described in detail herein. As shown in fig. 3, when the sensor module 8 is mounted on the water cup 7, the water cup further comprises a sealing ring 10 sleeved outside the main body 11, so as to ensure tightness between the sensor module 8 and the water cup 7.
Wherein the second sensor body 4 is disposed on the upper surface of the main body 11 and between the first extension portion 12 and the second extension portion 13, and the second sensor body 4 is disposed at a height lower than a light irradiation area (not shown in the figure) between the light emitting unit 21 and the light receiving unit 22, which corresponds to an area formed by irradiation of light of the infrared emitting tube and the infrared receiving tube in the horizontal direction; and/or the second sensor body 4 is provided on the upper surface of the first extension 12 and/or the second extension 13. This ensures that the operation between the second sensor body 4 and the first sensor body does not interfere with each other.
As shown in fig. 3 and 4, the second sensor body 4 in this embodiment is one and is a temperature sensor for detecting the temperature of water discharged from the dishwasher. The second sensor body 4 is provided on the upper surface of the main body 11 and is located between the first extension 12 and the second extension 13. Since the second sensor body 4 and the circuit board are both installed in the main body 11, the electrical connection of the second sensor body 4 becomes simpler. Therefore, compared with the prior dish washing machine, the novel dish washing machine has the advantages that each sensor is independently installed, the novel dish washing machine is simpler in structure, cost is saved, installation is easier, and installation efficiency is improved.
As shown in fig. 5, the temperature sensor in this embodiment is composed of a thermistor T, and the resistance of the thermistor T is output between the ports PT0 and PT1, so that the resistance of the thermistor T is converted into a temperature value by connecting the ports PT0 and PT1 with a controller (e.g., a singlechip); in addition, when the port DC5V inputs voltage, the light emitting unit 21 (i.e. infrared emitting tube) is electrified, and meanwhile, current is electrified to the light receiving unit 22 (i.e. infrared receiving tube) through the potentiometer RP1 and the current limiting resistor R2, the infrared receiving tube is conducted, the current obtains a high potential through the pull-down resistor R1 to supply the output port, when the dish washer discharges pollutants in water to block infrared light, the current flowing through the infrared receiving tube tends to zero at the zero output end, and the output port is connected with a controller (e.g. a singlechip), so that the turbidity can be converted through the voltage change of the output port.
Embodiment two:
as shown in fig. 6, unlike the first embodiment, the second sensor body 4 in this embodiment is provided at least in two and spaced apart from the upper surface of the main body 11.
When the second sensor body 4 in the present embodiment is also a temperature sensor, the detection accuracy can be improved by detecting a plurality of temperature sensors, and the abnormal control of the dishwasher caused by the abnormal detection of one or more temperature sensor data can be prevented.
Embodiment III:
unlike the first embodiment, at least two second sensor bodies 4 are located on the upper surfaces of the first extension 12 and the second extension 13.
As shown in fig. 7, the second sensor bodies 4 are two, and are located on the upper surfaces of the first extension portion 12 and the second extension portion 13, respectively. In order to realize that the second sensor body 4 is not interfered with the first sensor body when being mounted, the vertical projections of the second sensor body 4, the light emitting unit 21 and the light receiving unit 22 are not overlapped, so that the mounting of the first sensor body can be avoided; of course, the second sensor body 4 may be fixed to the upper end portions of the light emitting unit 21 and the light receiving unit 22 in advance when the light emitting unit 21 and the light receiving unit 22 are correspondingly mounted to the first extension portion 12 and the second extension portion 13, so that interference of horizontal light rays of the light emitting unit 21 and the light receiving unit 22 can be avoided.
When the second sensor body 4 in this embodiment is also a temperature sensor, the temperature sensor can better penetrate into the water discharged by the dishwasher when the sensor module 8 is mounted on the dishwasher, so as to improve the detection effect of the temperature sensor.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
