FIG. 1 is a schematic flow chart of a method for detecting clogging of a drain pipe of a dishwasher according to an embodiment of the present invention.
Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
The embodiment of the invention provides a method for detecting the blockage of a drain pipe, which is suitable for washing equipment of kitchen utensils; for example, it may be adapted to detect a blockage in the drain of a dishwasher. The present embodiment takes a dishwasher as an example, and describes a method for detecting clogging of a drain pipe of the dishwasher.
The dishwasher provided by the embodiment of the invention comprises a water tank, a drain pipe, a heater, a temperature sensor and a control unit. Wherein, the sink has the cavity, is used for holding the tableware and washing water of waiting to wash, and the tableware can be washed by the washing water repeatedly in the sink to make the tableware clean.
The heater can be arranged in the water tank and used for heating the washing water, the heater is in signal connection with the control unit, the control unit can control the working state of the heater, and when a user starts the dishwasher to enter a washing program, the heater can be adjusted to the heating state by default.
The heater provided by the embodiment can maintain constant power. For example, different washing programs selected by the dishwasher are different, different washing programs can correspond to different standard water levels, the heater can set different heating powers according to the set standard water level, and the heating power of the heater can be kept constant no matter what heating power is selected by the heater and the washing water is heated.
The temperature sensor is arranged in the water tank and is in signal connection with the control unit, and the temperature sensor is used for collecting the temperature of the washing water in the water tank and transmitting the temperature to the control unit. For example, the temperature sensor may collect the temperature of the washing water in the water tub in real time and transmit the collected temperature of the washing water to the control unit in real time, so that the control unit may obtain the temperature of the washing water in time.
The drain pipe is communicated with the bottom of the water tank and used for discharging sewage generated by washing in the water tank to the outside of the dish-washing machine, and the sewage contains a large amount of food residues and the like, so that the drain pipe is easy to block, and once the drain pipe is blocked, the normal work of the dish-washing machine can be influenced; it is therefore necessary to detect the clogging of the drain pipe.
As shown in fig. 1, the method for detecting the blockage of the drain pipe of the dishwasher provided by the embodiment specifically includes the following steps:
step S101: starting the dishwasher to enter a washing program and setting a standard water level of the washing program.
Specifically, when a user needs to use the dishwasher to wash dishes, the switch of the dishwasher is activated to put the dishwasher into a washing program. The washing program of the dishwasher may include a main washing program and a rinsing program, and different washing programs correspond to different standard water levels.
The standard water level in this embodiment is the standard amount of washing water required under the washing program; correspondingly, if no washing water is left in the water tank before water enters, the water level of the water tank under the washing program is the standard water level. It can be understood that the standard water level can be set according to the standard capacity of the water tank, and the preset standard capacity is unchanged no matter what washing program is selected; for example, the standard volume in a sink is 2.5L.
The washing program of the dishwasher is not limited to the main washing program and the first rinsing program, and the washing program can be set according to actual requirements. For example, a pre-draining process is provided before the main washing process, or a drying process is provided after a rinsing process is finished; this embodiment is not limited in this regard.
The present embodiment is preferred that the washing program of the dishwasher includes a pre-drain program, a main washing program and a rinsing program so as to be selected by the user. The pre-drainage program is arranged before the main washing program, so that the water tank of the dish-washing machine used last time can be conveniently cleaned, and the drain pipe can be dredged. In addition, the blocking of the drain pipe can be detected in the pre-drain process to avoid the malfunction when the tableware is added to the water tank and the formal washing is performed.
Step S102: and calculating a theoretical rising temperature value T' after heating for a preset time under the standard water level.
Specifically, after the user selects the washing program and sets the standard water level, the control unit may calculate the theoretical rising temperature value T' of the washing water according to the set standard water level, the constant power when the heater heats, and the preset time of heating.
Exemplarily, the washing water capacity in the tub during the main washing stage (when the dishwasher performs the main washing program) is 2.5L, the power of the heater when heating the washing water is constant, and the preset heating time of the heater may be 3 minutes; thus, the control unit may calculate a theoretical rising temperature value T' of the washing water after being heated by the heater for 3 minutes in the main washing stage according to the specific heat capacity of the washing water, the available heat amount.
The embodiment also provides another way for calculating the theoretical rising temperature value T' after heating for the preset time under the standard water level: under the normal drainage condition of the dishwasher, the heater heats the washing water under the standard water level in the water tank with constant power, and the theoretical rising temperature value T' of the washing water in unit time is obtained.
Specifically, under the condition of normal drainage of the dishwasher, the washing water capacity in the water tank of the first rinsing stage is set to be 2.5L, the washing water can be heated by the heater, and the power of the heater is constant in the heating process. For example, when the heater is operated for 1 minute, the washing water in the sump may be raised by 2 deg.C, so that the theoretical rising temperature value T' of the washing water per unit time may be obtained.
The process can be repeated for a plurality of times to obtain the average value of the theoretical rising temperature value T 'of the washing water in unit time, so as to ensure that the accurate theoretical rising temperature value T' can be obtained when a certain washing program of the dish-washing machine is detected.
For example, the dishwasher executes a rinsing program, the heater is preset for a heating time of 3 minutes, the other parameters are not changed, the only variable is the heating time, and the theoretical rising temperature value T' of the washing water in the corresponding water tank is 6 ℃.
It can be understood that, in the embodiment, the theoretical rising temperature value T 'of the washing water in the corresponding unit time under the normal condition of the dishwasher, the condition of a certain constant heating power and a standard water level, may be prestored in the control unit, so as to compare the actual rising temperature value T of the washing water with the theoretical rising temperature value T' in the following process, so as to determine whether the drain pipe of the dishwasher is normal.
Step S103: obtaining an initial temperature T of the washing water1。
Specifically, an initial temperature T of washing water entering a tub is detected using a temperature sensor provided in the tub1And the initial temperature T is measured1To the control unit. This embodiment can be after the washing water finishes intaking, detect the initial temperature of washing water again, and it can carry out a lot of detections to promote the accuracy of the initial temperature of the washing water that the control unit obtained.
Step S104: heating the washing water in the water tank for a preset time, and obtaining the current temperature T of the washing water after the washing water is heated for the preset time2。
The unit to be controlled obtains the initial temperature T of the washing water1Then, the heater may be controlled to heat the washing water. When the heater heats the washing water in the water tank, the heating power of the heater is kept constant; after the heater works for a preset working time, the temperature of the washing water is detected again by using the temperature sensor so as to obtain the current temperature T of the washing water2And the current temperature T of the washing water2Transmitted to the control unit, thereby controlling the current temperature T of the washing water of the unit2。
Step S105: calculating an actual rising temperature value T of the washing water, wherein T ═ T2-T1。
Specifically, the control unit obtains an initial temperature T of the washing water in the water tank1And the current temperature T of the washing water after heating for a predetermined time2The actual rising temperature value T of the washing water can be calculated, wherein T is T2-T1(ii) a The above calculation formula of the actual rising temperature value of the washing water may be prestored in the control unit, and the actual rising temperature value T of the washing water may be automatically calculated.
Step S106: comparing the actual temperature value T with the theoretical temperature value T'; if the actual rising temperature value T is smaller than the theoretical rising temperature value T', judging that the drain pipe is blocked and giving an alarm; and if the actual rising temperature value T is greater than or equal to the theoretical rising temperature value T', judging that the drainage of the drainage pipe is normal.
Specifically, the control unit compares the acquired actual rising temperature value T with a prestored theoretical rising temperature value T ', and judges the blockage condition of the drain pipe of the dishwasher according to the magnitude of the actual rising temperature value T and the prestored theoretical rising temperature value T'.
If the actual rising temperature value T is smaller than the theoretical rising temperature value T', the situation that the drain pipe is blocked before the washing procedure is carried out is indicated, and early warning needs to be carried out.
Because the drain pipe is blocked, the washing water in the water tank is not completely discharged, and residual washing water exists, so that when the current washing program is carried out and water is fed according to the set standard water level, the washing water in the water tank exceeds the standard water level. Under the condition of the set heating power, the heat quantity provided by the heater is unchanged, and the washing water in the water tank is increased compared with the washing water under the standard water level, so that the actual temperature rising value T of the washing water in the water tank is smaller than the theoretical rising temperature value T' after the heater works for the preset time.
On the contrary, if the actual rising temperature value T is equal to or greater than the theoretical rising temperature value T', it is indicated that the drainage of the drainage pipe is normal. It should be noted that, when the actual rising temperature value T is greater than the theoretical rising temperature value T ', the initial temperature may be increased due to the heat of the tableware itself, so that the final actual rising temperature value T is greater than the theoretical rising temperature value T', which does not affect the judgment of the blockage of the drain pipe.
For example, when the dishwasher performs a rinsing process in which a standard washing water capacity of the tub may be 2.5L, the heater operates for 1 minute and the temperature of the washing water may increase by 2 ℃ when the heater heats the washing water with a constant power under a normal drain condition. If the heating time set by the heater is 3 minutes in the first rinsing stage, the theoretical rising temperature T' of the washing water in the water tank is 6 ℃, and if the actually detected actual temperature rising value T of the washing water is between 3 and 4 ℃, the situation that the drain pipe is blocked is indicated, and an alarm is required.
According to the method for detecting the blockage of the drain pipe of the dish washing machine, provided by the embodiment of the invention, the washing water under the standard water level is heated according to the preset time through the temperature sensor arranged in the water tank and the heater capable of keeping constant power, the initial temperature and the current temperature after the heating for the preset time are detected through the temperature sensor, the actual rising temperature value T of the washing water is calculated, and the actual rising temperature value T and the theoretical rising temperature value T' are compared, so that whether the drain pipe is blocked or not is judged.
Compared with the scheme of detecting the blockage of the drain pipe of the dish-washing machine by the turbidity sensor in the related art, the embodiment of the invention monitors the blockage of the drain pipe by the existing temperature sensor, heater and the like of the dish-washing machine, has less influence of the dirt of the washing water, has high detection precision and can also avoid the problem of misjudgment; meanwhile, a turbidity sensor is not required to be additionally arranged, so that the detection cost can be saved.
On the basis of the above embodiment, the dishwasher further comprises an alarm device, which can be an alarm lamp arranged on the dishwasher; when the control unit judges that the drain pipe is blocked and gives an alarm, the control unit can control the alarm lamp to light up and flash so as to remind a user that the drain pipe of the dish washing machine is blocked. It will be appreciated that the control unit may disable the dishwasher and alarm in the event of a blockage in the drain of the dishwasher.
Further, the control unit provided by the embodiment includes a memory and a processor, wherein the memory stores a control program of the dishwasher which can be operated by the processor; the above-described method of detecting clogging of a drain pipe can be implemented when the control program is executed by the processor. Correspondingly, when the blockage condition of the drain pipe of the dishwasher is detected, the blockage condition can be detected in any one of the pre-drainage program, the main washing program and the rinsing program of the dishwasher.
On the basis of the above embodiment, the dishwasher further includes a display panel having a plurality of operation function keys to allow a user to select different washing programs. The display panel is in signal connection with the control unit and can display all washing programs, the washing programs currently executed by the dishwasher and the current washing program process; the display panel can also display the temperature of the washing water in the water tank and the state information of the drain pipe.
