Application overview

During the washing process, the dishwasher is pressurized by the washing pump, and the water is sprayed from the nozzle. The direction of the output is perpendicular to the horizontal radial direction to obtain a large tangential acceleration. The washing pump does work, and the sprayed water flow has a large The kinetic energy of the spray arm, the rapidly sprayed water flow gives enough tangential force to the spray arm, which is the principle of the spray arm rotation.

After the dishwasher has been used for a long time, the nozzles of the washing spray arms will be blocked, which will reduce the water output and affect the washing effect.

Therefore, when it is judged that the flow channel is blocked, it is necessary to carry out self-cleaning of the nozzle, but blindly increase the water pressure, so that the blockage is only removed under the action of water pressure, the effect is not good, either the cleaning time is long, or the final Automatic cleaning cannot be done, only manual cleaning is possible.

Resonance is the tendency of a physical system to absorb more energy from the surrounding environment at its natural vibrational frequency. Usually, resonance can be harmful because it causes external energy to act directly on the molecule. , atomic level, and continuously absorb energy, causing it to undergo violent displacement in a small range. Therefore, the resonance phenomenon will destroy the unity between particles, and it is easy to cause the entire system to collapse instantly, which will bring destruction.

Example 1

As shown in Figure 1, a specific embodiment of a method for cleaning up flow channel blockage includes:

Step S101: acquiring the natural frequency of the blockage in the flow channel;

Step S103: acquiring the pulse frequency of the medium flow in the flow channel;

Step S105: Control the pulse frequency according to the natural frequency, so that the medium flow and the blockage resonate.

In the above-mentioned method for clearing the blockage of the flow channel, the medium flow may be a water flow. After the blockage vibrates, due to the physical characteristics of its own composition, size and shape, the vibration that originally started with multiple frequencies will gradually vibrate at a certain frequency, which is the natural frequency of the blockage. When the medium flow passes through the blockage, the medium flow will add a vibration to the blockage, and the vibration generated by the impact of the medium flow on the blockage can form a pulse. When the pulse frequency of the medium flow is the same as the natural frequency of the blockage, the vibration of the blockage The amplitude reaches the maximum, so that the resonance phenomenon occurs between the medium flow and the blockage.

When the medium flow and the blockage resonate, the medium flow can act on the most microscopic level of the blockage in the most precise way, so that the blockage can continuously absorb energy at each basic unit of this level, and then undergo a violent displacement, thereby affecting the flow of the blockage. Blockages can be extremely damaging.

Therefore, the powerful energy generated by the resonance between the medium flow and the blockage can realize that the flow channel can be dredged only by the impact force of the water flow without the water pressure being too high.

Specifically, as shown in Figure 2, the natural frequency of the blockage in the flow channel is obtained, which specifically includes:

Step S201: put the blockage model of the blockage and the vibration source together;

Step S203: changing the vibration frequency of the vibration source to make the blockage vibrate;

Step S205: Obtain the natural frequency according to the peeling condition of the blockage during vibration.

The acquisition of the natural frequency of the blockage in the flow channel can be carried out by a conventional excitation test. The liquid can be carried out by the above-mentioned step of acquiring the natural frequency of the blockage in the flow channel. Among them, put the blockage model of the blockage together with the vibration source, control the vibration source to vibrate, and change the vibration frequency of the vibration source. The frequency at which the best case of spalling occurs is the frequency at which the blockage vibrates near the maximum amplitude, which is the natural frequency of the blockage model, that is, the natural frequency of the blockage. Of course, there will be a certain deviation, but as long as the vibration frequency of the vibration source is close to the natural frequency, and the greater the degree of proximity, the greater the possibility of resonance. Therefore, when the pulse frequency of the medium flow is similar to the natural frequency of the blockage, it will cause damage to the blockage.

Specifically, the natural frequency is the self-vibration frequency of the blockage in the axial direction at the blockage position. Among them, the natural frequency of the blockage in the axial direction can be obtained by a conventional excitation test, and the natural frequency of the blockage in the axial direction can also be obtained by the above method. The axial direction of the blockage at the blockage position is the flow direction of the medium flow at the blockage position, so that resonance can be achieved as soon as possible in the flow direction, and the time for cleaning the flow channel is reduced.

Example 2

As shown in FIG. 3 is a specific embodiment of the washing method of the washing equipment, and the washing method of the washing equipment includes:

Step S301: controlling the washing pump 7 of the washing equipment to supply water to the flow channel;

Step S303: obtaining blockage information in the flow channel;

Step S305: when the flow channel is blocked, execute the above-mentioned method for clearing the flow channel blockage;

Step S307 : when the flow channel is not blocked, exit from executing the above-mentioned flow channel blockage cleaning method.

In the above washing method for washing equipment, the washing equipment includes a washing pump 7, and the washing pump 7 can supply water into the flow channel for washing. First, it is judged whether the washing pump 7 of the washing equipment is performing water supply operation, so as to judge whether it is necessary to clear the blockage of the flow passage when the washing equipment is washing. Then, it is determined whether the flow channel is blocked. At this time, by obtaining the blockage information in the flow channel, it is possible to determine whether the flow channel is blocked. When it is judged that the flow channel is blocked, the process of the flow channel blockage cleaning method is started, so that the blockage can be removed as soon as possible to ensure the normal progress of washing. If the blockage has been cleared, it will be judged that the flow channel is not blocked, then exit the flow channel blockage cleaning method process, and then return to the normal washing process to complete the normal washing process of the washing equipment.

In this way, when cleaning the flow channel of the dishwasher, it is only necessary to change the pulse frequency of the water flow, without adding hardware assistance, and the flow channel blockage can be cleaned through program control, which not only saves costs, but also solves the need for users to regularly The problem of cleaning up the spray arm has been improved, and the user experience has been improved.

Specifically, the method for clearing blockage of the flow channel further includes: controlling the rotational speed of the washing pump 7 to change within a preset period to obtain the pulse frequency of the medium flow in the flow channel.

In the above-mentioned method for clearing blockage of the flow channel, by changing the rotation speed of the washing pump 7 in a unit time, different water flow rates can be obtained, and the frequency of the water flow is also different. According to the experiment, the corresponding relationship between different water flow and different water flow frequency can be obtained, which is roughly a positive correlation law. Therefore, by changing the rotational speed of the washing pump 7, different water flow rates can be obtained, and the changing water flow rates within the preset period will form a pulsed water flow with a certain frequency.

Specifically, as shown in FIG. 4 , the blockage information includes the blockage occurrence information or the blockage non-occurrence information, and the blockage information in the flow channel is obtained, which specifically includes:

Step S401: acquiring the noise information of the washing chamber 6;

Step S403 : when the noise information is outside the preset noise range, generate blockage occurrence information;

Step S405: When the noise information is within the preset noise range, generate no blockage information.

In the above-mentioned method of acquiring the clogging information in the flow channel, the washing chamber 6 will make noise during washing, among which, the washing in the case where the flow channel of the nozzle 5 is not blocked is different from that when the flow channel of the nozzle 5 is blocked. Washing, there is a clear difference between the two in terms of noise. Therefore, a preset noise range is set, and the obtained noise information is compared with the preset noise range. When the noise information is outside the preset range, it means that the noise is large, the flow channel is blocked, and the ejection of the nozzle 5 is affected. The flow rate of the water flow, then a blockage message will be generated. When the noise information is within the preset range, it means that the noise is within an acceptable range, and the flow channel may be blocked, but it will not affect the flow rate of the water jet from the nozzle 5, so that the washing chamber 6 can still be completed normally. When washing, the message that no blockage has occurred will be generated. If the flow channel blockage cleaning process has not been entered at this time, continue to perform normal washing; if the flow channel blockage cleaning process has just been performed at this time, exit the flow channel blockage cleaning process and continue normal washing.

Specifically, as shown in Figure 5, acquiring the blockage information in the flow channel also includes:

Step S501: obtaining the blockage degree of the blockage according to the noise information;

Step S503: When the congestion degree exceeds 50%, generate congestion information.

In the above-described method of acquiring the clogging information in the flow passage, the clogging information or the non-clogging information is generated according to the clogging degree of the clogging. When all the flow channels are blocked, the blockage degree can be set to 1, and when there is no blockage at all, the blockage degree can be set to 0. Among them, when the clogging degree reaches 30%, it will affect the water flow of the nozzle 5 out of the spray arm 1. Therefore, the normal washing and the clogging degree of the washing noise does not exceed 30% is the preset noise range, and a margin of 20% can be reserved as an allowance. Error range, it is easier to obtain blockage information in the flow channel. Therefore, it is set that the congestion level exceeds five as a node for generating congestion information. When the blockage of the flow channel reaches 50% to 70%, the water flow can still be sprayed from the nozzle 5 , but the water flow at this time is small and the water pressure is higher, which will generate more noise in the washing chamber 6 . When the clogging degree reaches more than 80%, the water flow can no longer drive the spray arm to rotate, and the noise will be lower than normal washing. Therefore, the degree of congestion can also be classified by the noise information. Obtain the blockage degree by other means, such as the interception area of the flow channel.

The noise information includes decibels, and the noise range includes the decibel range. The decibel information can be acquired through a decibel detection device, such as a decibel sensor, and the acquired decibel information can be compared with a preset decibel range, which is simple and reliable.

The control system 8 is connected in communication with the washing pump 7 to obtain the pulse frequency of the medium flow in the flow channel, and the control system 8 is suitable for obtaining the blockage information and the natural frequency of the blockage in the flow channel. When the control system 8 judges that the flow channel is blocked, The control system 8 controls the pulse frequency of the medium flow delivered by the washing pump 7 according to the natural frequency, so that the medium flow resonates with the blockage.

In the above washing equipment, the spray arm 1 is arranged in the washing chamber 6 , and the spray arm 1 communicates with the nozzle 5 . Among them, a plurality of nozzles 5 are respectively provided on the spray arm 1, and the nozzle 5 has a flow channel, and the flow channel of the nozzle 5 communicates with the flow channel of the spray arm 1, so that water can be supplied to the washing chamber 6 through the nozzle 5. The control system 8 can control the rotational speed of the washing pump 7 so as to obtain and control the pulse frequency of the water flow delivered by the washing pump 7 .

Furthermore, the washing apparatus further includes a noise detection device 2, which is arranged on the cavity wall of the cavity, and is suitable for detecting the noise in the washing cavity 6 and sending noise information. Wherein, the control system 8 is also connected in communication with the noise detection device 2, and the control system 8 is adapted to obtain the noise information sent by the noise detection device 2, and obtain blockage information according to the noise information.

The tuyere 4 and the noise detection device 2 in the above-mentioned washing equipment are both arranged on the cavity wall of the cavity, and the control system 8 is connected to the noise detection device 2 and the washing pump 7 in communication respectively, so that the control system 8 can judge whether the occurrence of the occurrence is based on the noise information. Blockage, when the blockage occurs, the control system 8 controls the washing pump 7 to perform the steps of the cleaning method for the washing equipment described above.

In the above washing equipment, the washing equipment includes a dishwasher, and the noise detection device 2 may be a decibel detection sensor. The washing chamber 6 is provided with a spray arm 1 , and the flow channel of the nozzle 5 communicates with the flow channel in the spray arm 1 . A water outlet 3 is provided below the spray arm 1 for discharging the sewage after washing. By adding a decibel detection sensor to the inner wall of the washing chamber 6, the washing noise during the washing process can be detected, and it can be judged whether the washing noise is within a suitable range, and the suitable range is the preset noise range. With reference to FIG. 6 , it is judged whether the spray arm 1 has been blocked by judging whether the noise is within the preset noise range, and whether the self-cleaning program needs to be started for the degree of blockage. Among them, the blockage of the flow channel of the nozzle 5 is generally a mixture of calcium and magnesium ion deposits and sediment. When the pulse frequency of the water flow is similar to the natural frequency of the blockage, the water flow can quickly and efficiently flush out the blockage. Then, by judging the washing sound, the control system 8 knows that the self-cleaning has been completed, and will exit the self-cleaning program and resume normal washing.
