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

As shown in fig. 1, a specific embodiment of a washing control method includes:

step S101: when the washing cavity door of the washing cavity 11 is opened, the load is controlled to stop working;

step S103: when the washing cavity door is closed, the washing cavity 11 is controlled to be in a negative pressure state;

step S105: the washing operation is started under a negative pressure state.

The opening of the washing chamber 11 or the closing of the washing chamber 11 is usually performed halfway after the normal washing operation is interrupted. In the case of normal washing, if the washing chamber door is not opened halfway, the steps of the above-described operation method need not be performed.

The washing operation can be performed in the washing chamber 11, and the load includes all the working units in the washing chamber 11, including the washing system 2, the drying system, and the like. After closing washing chamber door, control washing chamber 11 is in under the negative pressure state to when opening washing operation again under the negative pressure state, because be in the negative pressure state in washing chamber 11, pressure in the washing chamber 11 is less, makes washing chamber door of washing chamber 11 not expanded suddenly, has improved the safety in utilization, has also improved user experience.

Further, as shown in fig. 2, when the door of the washing chamber is opened, the controlling the load to stop working specifically includes:

step S201: when the washing cavity door is opened, an opening signal is acquired;

step S203: and controlling the load to stop working according to the opening signal.

In the above steps, when the washing cavity door is opened, the opening signal of the washing cavity door is obtained, and the load is controlled to stop working according to the opening signal, so that the reliability is improved.

Further, as shown in fig. 3, when the washing chamber door is closed, the washing chamber 11 is controlled to be in a negative pressure state, which specifically includes;

step S301: when the washing cavity door is closed, a closing signal is obtained;

step S303: the washing chamber 11 is controlled to be in a negative pressure state according to the closing signal.

In the above steps, when the washing cavity door is closed, the closing signal of the washing cavity door is obtained, and the washing cavity 11 is controlled to be in a negative pressure state according to the closing signal, so that the response can be timely realized, and the reliability is improved.

Further, as shown in fig. 4, controlling the washing chamber 11 to be in a negative pressure state specifically includes:

step S401: controlling the washing chamber 11 to exhaust outwards;

step S403: when the washing chamber 11 is exhausted for the first time, the washing chamber 11 is in a negative pressure state.

In the above steps, the pressure control of the air in the washing chamber 11 can be realized by exhausting the air in the washing chamber 11 out of the washing chamber 11, and when the air starts to be exhausted out of the washing chamber 11, the pressure in the washing chamber 11 is gradually reduced, which is easy to realize. The first time can be obtained by timing and can be regarded as the time which lasts after the exhaust is started, and is easy to obtain. When the time for exhausting the gas from the washing chamber 11 is maintained to the end of the first time, it can be determined that the washing chamber 11 is in a negative pressure state, so that the washing operation is started in the negative pressure state, and the washing chamber door is not squeezed from the inside to the outside to expand the washing chamber door.

Further, the washing operation is started under the negative pressure state, and the method specifically comprises the following steps: the washing operation is started after the first time, and the washing operation is controlled more easily.

The washing control method further includes: when the washing operation is maintained for the second time, the exhaust of the washing chamber 11 to the outside is stopped. It is understood that after the washing operation is started, air will enter the washing chamber 11 along with it, so that the pressure in the washing chamber 11 is increased. At a second time after the washing operation is started, the washing chamber 11 is still exhausting gas outwards, which can balance the increased pressure occurring at the beginning of the washing operation. That is, after the washing chamber door is closed, the time for discharging the pressure in the washing chamber 11 is the sum of the first time and the second time, so that the pressure relief can be ensured, the washing door body cannot expand, the normal operation of the washing program can be ensured, and the total washing time cannot be prolonged.

The second time is 1 second to 150 seconds, and/or the first time is 1 second to 100 seconds.

The first time may be denoted as t1, and the second time may be denoted as t 2. Considering that if the time is short, the pressure relief is not facilitated, the door body expansion risk still exists, and if the time is too long, the pressure relief is not influenced, but the total time of the washing program is influenced, so that the first time t1 is controlled to be 1 second to 100 seconds, and the second time t2 is controlled to be 1 second to 150 seconds, so that the pressure relief requirement of the washing cavity 11 can be met, and the total time of washing can not be prolonged.

The washing chamber 11 is located in the inner container 1, and a washing chamber door is opened on the inner container 1 so as to open the washing chamber 11 or close the washing chamber 11. The washing system 2 may be partially located within the washing chamber 11 to wash the objects placed within the washing chamber 11. The controller 4 controls the negative pressure system 3 to generate negative pressure and controls the washing system 2 to wash, thereby realizing the automatic washing operation of the washing device 100. The negative pressure system 3 can generate negative pressure in the washing chamber 11, so that when cold air enters the washing chamber 11 in a high-temperature state and is instantaneously evaporated to increase the air pressure in the washing chamber 11, the washing chamber 11 cannot expand a door of the washing chamber in a negative pressure state, and the use safety and reliability of the washing device 100 can be ensured.

Further, as shown in fig. 6, the washing apparatus 100 further includes: and the door opening and closing detection module 12 is connected with the controller 4 in a communication way. When the washing chamber 11 is opened, the door opening and closing detection module 12 acquires opening information and sends the opening information, when the washing chamber 11 is closed, the door opening and closing detection module 12 acquires closing information and sends the closing information, the controller 4 controls the load to stop working according to the opening information sent by the door opening and closing detection module 12, the controller 4 controls the negative pressure system 3 to be opened according to the closing information sent by the door opening and closing detection module 12, and controls the washing system 2 to be opened for washing operation after the negative pressure system 3 is opened for a first time, and closes the negative pressure system 3 after the washing system 2 is opened for a second time.

The door opening and closing detection module 12 may include a magnetic switch and a mechanical travel switch, and may detect the opening state or the closing state of the washing chamber door through the change of current or voltage in the control circuit, with reliable detection results.

Further, as shown in fig. 7, the negative pressure system 3 includes an exhaust fan 31, and an air inlet of the exhaust fan 31 is communicated with the washing chamber 11.

The exhaust fan 31 exhausts the air in the washing chamber 11 through the air inlet, so as to reduce the pressure in the washing chamber 11, and the inside of the washing chamber 11 can reach a negative pressure state after exhausting for a period of time. By timing the opening time of the exhaust fan 31, the timing time is easily obtained.

Example 3

As shown in FIG. 7, one embodiment of a dishwasher 10 includes: the washing apparatus 100 as above; and/or the above-described washing control method may be performed.

The dishwasher 10 described above further comprises a drying system, a water inlet system and a water drainage system. The inner container 1 of the washing device 100 includes a washing chamber 11, a washing chamber door, a door opening and closing detection module 12, a water tank 13, a first air hole 14 and a second air hole 15. The washing chamber 11 is located in the inner container 1, and a washing chamber door is opened on the inner container 1 so as to open the washing chamber 11 or close the washing chamber 11. The negative pressure system 3 of the washing device comprises an exhaust air fan 31, and the washing system 2 of the washing device comprises a spray arm 21, a cutlery basket 22, a washing pump 23 and a first heater 24. The drying system includes an air intake fan 51, a second heater 52, and a temperature sensor 53. The water inlet system comprises a water inlet pipe 61, a solenoid valve 62 and a water inlet flow meter 63. The drain system includes a drain pipe 71, a drain pump 72, a drain flow meter 73, and a turbidity sensor 74.

Wherein, the bottom of the washing chamber 11 is provided with a water tank 13, the side wall of the inner container 1 is provided with a first air hole 14 and a second air hole 15, the first air hole 14 is provided with an exhaust fan 31, and the second air hole 15 is provided with an intake fan 51 and a second heater 52.

The water inlet system and the water discharge system are respectively arranged below the water tank 13. Wherein, the water inlet pipe 61 can supply water to the water tank 13 by opening the electromagnetic valve 62 on the water inlet pipe 61, and the water supply amount can be controlled by the water inlet flow meter 63. The water entering the water tank 13 is pumped out by a washing pump 23, the water pumped out by the washing pump 23 firstly enters a first heater 24 to be heated and then enters a spraying arm 21, the spraying arm 21 is arranged in the washing cavity 11, the spraying arm 21 sprays water while rotating to clean the tableware in the washing cavity 11, and the tableware can be placed in a tableware basket 22.

In the operation of the dishwasher 10, the sink 13 disposed at the bottom of the inner container 1 of the dishwasher 10 collects water and food residues after washing dishes, and the washing water falling into the sink 13 is pumped into the spray arm 21 by the washing pump 23 again to form a circulation water path. In normal program operation, circulating water collected from the water tank 13 is conveyed into a water path system through the washing pump 23, then enters the spraying arm 21 to form high-pressure water columns at spraying holes to be sprayed out, so that tableware is washed, and washing water flows into the bottom from the tableware and the wall of the inner container 1 by means of gravity and then flows back to the water tank 13.

Wherein, the turbidity sensor 74 is arranged in the water tank 13, when the turbidity sensor 74 detects that the turbidity of the water in the water tank 13 exceeds a predetermined value, the water is discharged through the drainage pump 72 connected to the drainage pipe 71. The amount of water discharged can be controlled by the water discharge flow meter 73.

When the dishwasher 10 is used for washing, if the normal washing process is carried out, the washing water is gradually and slowly heated, and the exhaust hole of the dishwasher can gradually release the pressure, so that the internal and external balance of the washing cavity 11 is maintained, and the instantaneous pressure in the washing cavity 11 cannot be overlarge.

However, the dishwasher is performed in a high temperature state during washing for a certain period of time. In a high temperature state, if the door of the washing chamber of the dishwasher is opened, the temperature of the air in the washing chamber 11 is rapidly lowered, and the temperature of the water inside is slowly lowered. After the door is closed again, the program is normally operated, and the washing pump 23 of the dishwasher sprays hot water, so that the cold air entering the washing chamber 11 is rapidly heated and expanded, resulting in a momentary increase in the air pressure in the washing chamber 11. However, the internal vents of the dishwasher are not as time to vent, thus causing the washing chamber door to expand.

Therefore, if the washing cavity door of the dish washing machine is opened halfway and then closed, the air pressure of the washing cavity 11 is firstly decompressed through the negative pressure system 3 of the washing device, and then the washing system 2 of the washing device is started to carry out washing operation, so that the safety of the dish washing machine in the use process can be ensured, and the experience satisfaction degree of a user is improved.

When the washing is finished, the drying system can be started, the second heater 52 heats the air entering through the air inlet fan 51, and the hot air enters the washing chamber 11 to dry the tableware. The temperature inside the washing chamber 11 is sensed by the temperature sensor 53 so that the first and second heaters 24 and 52 can be adjusted.

The above-mentioned drain pump 72 is mainly responsible for discharging the washing circulating water out of the inner container 1 at the end of each washing stage, the flow meter is responsible for detecting the accuracy of the water inflow, and the components such as the air intake fan 51 and the air exhaust fan 31 can dry the tableware.

As shown in fig. 8, the washing program of the dishwasher generally includes important steps such as a water inlet stage, a washing stage, a water discharge stage, a drying stage, and the like, and when the water inlet of the dishwasher is completed, the following steps can be performed:

step S501: the dishwasher operates normally for washing.

In this step, the washing pump 23 is activated to form a high-pressure water column to spray-wash the dishes.

Step S503: and judging whether a door opening signal is detected or not.

In the whole washing program operation process, when the control circuit does not detect a door opening signal, the washing machine can normally operate to the end, and if the door opening signal is detected in the operation process, all loads can be immediately stopped to work. Step S505: and when the door opening signal is detected, controlling all the loads to stop running.

Step S507: and judging whether a door closing signal is detected.

And when all the loads stop running, entering a standby state. If the door closing signal is not detected, the standby state is maintained until the door closing signal is detected, and the operation is not resumed.

Step S509: and (4) exhausting for a fan time t 1.

When the door closing signal is detected to return to operation, the circuit controls the operation time t1 of the exhaust fan 31 preferentially to exhaust the inner container 1, so that the inner container 1 forms negative pressure.

Step S511: the fan/wash pump 23 is simultaneously operated for a time t 2.

After a negative pressure environment is formed, the washing pump 23 is started, and works for a time t2 with the exhaust fan 31 to balance the pressure of the inner container 1, so that the door body is prevented from being expanded instantly when the pressure is high.

Step S513: the program runs normally.

After the washing pump 23 and the exhaust fan 31 are started and simultaneously operated for a time t2, the tableware is washed by returning to the normal state until the program is finished, the special fan operating time t1 is between 1 second and 100 seconds, and the washing pump 23 alone or the washing pump 23 and the fan are simultaneously operated for a time t2 between 1S and 150S.

It can be known that, when the tableware is added after the dish washer is opened midway, the washing pump 23 is started only after the washing pump is started, the air exhaust fan 31 is started to exhaust air for a period of time, the inner container 1 forms negative pressure, and then the washing pump 23 is started after the tableware is added after the misoperation of a user in the operation process, the air exhaust fan 31 continues to work at the moment, the pressure of the inner container 1 is small, so that the phenomenon that the pressure of the inner container 1 is too large, and the door body is expanded instantly to cause the abnormal termination of the dish washer can be avoided.
