Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
A garbage disposer in accordance with an embodiment of the present invention is described below with reference to the accompanying drawings.
Fig. 1 is a block diagram of a garbage disposer in accordance with one embodiment of the present invention. As shown in fig. 1, the garbage disposer 100 includes: the crusher 110, the crusher motor 120, the water inlet motor 130, the micro switch 140, the power-on detection sensor 150, the water pressure detection sensor 160 and the controller 170.
Wherein the pulverizer motor 120 is used to drive the pulverizer 110, i.e., to control the operation or stop of the pulverizer 110.
The water inlet motor 130 is used for controlling the water inlet valve, namely controlling the opening or closing of the water inlet valve, so as to realize water inlet or stop water inlet.
The micro switch 140 is used to control the garbage disposer, i.e., to control the start or stop of the garbage disposer.
The power-on detection sensor 150 is used to detect whether the garbage disposer is powered on and generate a power-on detection value. That is, when the garbage disposer is powered on, the power-on detection sensor 150 is used to detect whether the garbage disposer is powered on normally, and sends the collected power-on detection value to the controller 170. Specifically, for example, when the collected power-on detection value is smaller than a preset voltage value, it is determined that the garbage disposer is not powered on normally.
The water pressure detection sensor 160 is used to detect the water pressure entering the waste disposer and generate a water pressure detection value. That is, the water pressure detecting sensor 160 is used to detect whether the water pressure of the waste disposer is normal, and transmit the collected water pressure detection value to the controller 170. Specifically, for example, when the collected water pressure detection value is smaller than a preset water pressure value, it is determined that the water pressure of the waste disposer is abnormal.
The controller 170 is used to control the pulverizer motor 120 and the water intake motor 130 according to the power-on detection value and the water pressure detection value. That is, the controller 170 reasonably controls the components such as the crusher motor 120 and the water inlet motor 130 according to the power-on condition (whether power-on is normal) and the water pressure condition (whether water pressure is normal) of the garbage disposer, so as to ensure the safe use of the garbage disposer.
Specifically, when an abnormality occurs in the power-on detection sensor 150, that is, the garbage disposer is abnormally powered on (for example, a user performs a power-off operation), the controller 170 controls the shredder motor 120 to stop and controls the water intake motor 130 to stop after a delay of a preset time.
On the other hand, when the water inflow detection sensor is abnormal, that is, the water pressure of the garbage disposer is abnormal, the controller 170 controls the crusher motor 120 to stop and alarm. Specifically, the alarm is given, for example, by a buzzer.
Further, in one embodiment of the present invention, as shown in connection with fig. 2, the waste disposer also includes a water leakage detection sensor 180. The water leakage detection sensor 180 is used to detect whether the waste disposer is leaking water. Specifically, when abnormality occurs in the water leakage detection sensor 180, that is, when the garbage disposer leaks, the controller 170 controls the pulverizer motor 120 and the water inflow motor 130 to stop, and gives an alarm. Specifically, the alarm is given, for example, by a buzzer. In addition, in different abnormal situations, the alarm mode is different, for example, the alarm can be sounded according to abnormal data of different sensors, when a plurality of types of abnormalities exist, the alarm can be sounded alternately at different frequencies, and at this time, the controller 170 will not start the load until the alarm is released. For example, when the water pressure detection sensor 160 is abnormal, that is, the water pressure of the garbage disposer is abnormal, a first preset frequency beeping sound is emitted to alarm, and when the water leakage detection sensor 180 is abnormal, that is, the garbage disposer leaks water, a second preset frequency beeping sound is emitted to alarm, so that a user can clearly distinguish abnormal types, and corresponding measures can be taken in time conveniently.
Further, in one embodiment of the present invention, the garbage disposer further includes a motor overload detection unit (not shown). And a motor overload detecting unit for detecting whether the crusher motor 120 is overloaded. Specifically, when an abnormality occurs in the motor overload detecting unit, that is, the crusher motor 120 is overloaded, the controller 170 controls the water feed motor 130 to stop and alarm. Specifically, the alarm is given by, for example, sounding a third preset frequency through a buzzer, so that the user can distinguish the abnormal types.
In one embodiment of the present invention, when the waste disposer is normal, if the water is sensed by the water-free pressure switch, the micro switch 140 is pressed (turned on), the water inlet valve is opened to automatically feed water, and the shredder 110 is powered on. If the water is sensed by the water-free pressure switch, the micro switch 140 is pressed down (turned off) again, and the crusher 110 is immediately powered off to stop running, and at the same time, the water inlet valve is closed to stop automatic water inlet after waiting for a preset time. And as long as the anhydrous pressure switch senses no water, the whole garbage disposer can stop automatically feeding water.
On the other hand, if it is detected that the garbage disposer is powered up normally and the water pressure is normal, the controller 170 controls the pulverizer motor 120 and the water intake motor 130 to be turned on, i.e., the garbage disposer is operated normally.
In one embodiment of the present invention, when the power-on detection sensor 150 detects a power failure, the controller 170 controls the water inlet motor 130, the shredder motor 120, and the micro switch 140 such that the water inlet valve is closed, the micro switch 140 is opened, and the shredder 110 is not powered on and not operated.
In one embodiment of the present invention, when the water pressure detecting sensor 160 detects a water cut, the controller 170 controls the water inlet motor 130, the pulverizer motor 120, and the micro switch 140 such that the water inlet valve is closed, the micro switch 140 is opened, and the pulverizer 110 is not powered on to be not operated.
Specifically, in the case of an abnormality of the garbage disposer, when the power is suddenly cut off, the water inlet valve is controlled to be closed, the micro switch 140 is opened, and the pulverizer 110 is not energized and is not operated. Further, when the incoming call suddenly comes, the water inlet valve is closed, the micro switch 140 is in an on state, the pulverizer 110 is not electrified and is not operated, if a user needs to press the micro switch 140 once to close the pulverizer, and the pulverizer is normally started to be used once again.
When the water is suddenly cut off, the garbage disposer is powered off, the water inlet valve is controlled to be closed, the micro switch 140 is in an on state, and the pulverizer 110 is not powered on and does not operate. Further, when water suddenly comes, the garbage disposer is powered on, the water inlet valve is closed, the micro switch 140 is in an on state, the pulverizer 110 is not powered on and does not operate, if a user needs to press the micro switch 140 once to close the pulverizer, and then the pulverizer is normally started to be used once again.
When the garbage disposer is shut down for protection, the water inlet valve is controlled to be closed, the air switch is in an open state, the garbage disposer is not electrified and does not operate, if a user needs to press the air switch once to close the garbage disposer, and the garbage disposer is normally opened for use after being pressed once again.
Further, in one embodiment of the present invention, as shown in connection with fig. 2, the garbage disposer further includes: a first power module 190 and a second power module 200. The first power module 190 is configured to supply power to the waste disposer, and the first power module 190 includes a conversion device configured to convert ac power to dc power for powering the waste disposer. The second power module 200 is used to power the shredder motor 120 and the water intake motor 130. Specifically, the second power module 200 supplies alternating current to the shredder motor 120 and the water intake motor 130.
In summary, according to the garbage disposer in the embodiment of the invention, the power-on condition of the garbage disposer is detected by the power-on detection sensor 150, the water pressure condition of the garbage disposer is detected by the water pressure detection sensor 160, and the components such as the crusher motor 120 and the water inlet motor 130 are correspondingly controlled according to the power-on condition and the water pressure condition of the garbage disposer, so that the garbage disposer can be protected when the motor is abnormally started, malfunction and water leakage occur, the safe use of the garbage disposer is ensured, and the safety is improved.
