[PConline Tips] We all know that when home appliances run more or less, they will make some noises. This is understandable. However, if some of the sounds that should not have existed, it will attract our attention. Once these sounds have become noises, it will affect our normal rest. Secondly, this kind of sound will indicate that the machine has appeared. Some degree of failure reminds us that we need to carry out maintenance and repair in order to avoid hidden dangers. Today, we detectives of home appliances will have to dig around home appliance noise killer!
Strange sounds from the living room in the middle of the night
"The culprit" was actually it!
In the last week's time, Xiao Bian set out from home, rushed to the heights of the masses with large and small families, and finally returned to the embrace of our grand Guangzhou. The day was not an ordinary one. So Xiao Bian decisively took a hot shower and went to bed early to meet the start of the new year.
Noise reaches 56.8 dB
In the middle of the night, just as Xiao Bian had been sleeping and dreaming, the strange sound came from the living room. It was like the fan was stuck by some objects during the rotation. Xiao Bian thought that it was still a great New Year. Will not be so fierce? Or is there a thief entering the house? Hesitated for a long time, Xiao Bian finally got up to the living room that did not see fingers, incidentally picked up a Philips S7780 electric razor for self-defense weapons, after all, Xiaobian University learned half a semester Wing Chun, to deal with small The thief is enough! Go to the living room, turn on the lights, did not find suspicious traces, but found that "the culprit" turned out to be it - refrigerator!
Properly raise the bottom four feet of the refrigerator
The original bastard who slept in the middle of the night arguing that he could not sleep well turned out to be this refrigerator. Then why did it make such a noise? Observed carefully, it turned out that the two supporting feet at the bottom of the refrigerator were not adjusted, causing the refrigerator to lean forward. Make small adjustments to adjust the bottom four feet of the refrigerator, until the minimum noise is fixed, and then properly raise the four feet about 3-6cm, so that the air convection space at the bottom of the refrigerator increases, is conducive to the dispersion of the compressor and other parts of the sound, In a word, keep the balance on the four legs of the refrigerator.
Adjusted refrigerator noise value is reduced to 46.7 dB
In addition to four-foot imbalance is the "culprit" caused by noise in the refrigerator, the looseness of the screws inside the refrigerator caused resonance is also another "culprit" to create a strong noise. Therefore, it was found that the refrigerator emits a noticeable noise when it is cooling. You can try to press the compressor by hand. If the noise is significantly reduced, the noise raised by the hand is increased. Generally, the unevenness of the force or the looseness of the bolts is fixed on the base of the compressor. The compressor base plate is not firm. Adjust and tighten the connecting part screws and replace the lost elastic gasket.
It does not welcome me?
The detective Xiaobian recently moved into a new house, so the home appliances in the new house are also in a run-in period. At the same time, the home appliances also cooperate with the small make up to create a wide range of problems from time to time, this does not, The washing machine rang again! What is what happen?
Xiaobian home washing machine
Originally moved into a new house with a washing machine, Xiao Bian can completely bid farewell to the “hand rub + foot†laundry mode, is very much to be happy! However, in the face of Xiao Bian’s “new owner,†washing machines do not seem to buy it. When the washing machine is in the process of washing, you can hear the sound of a "click" from inside the cabinet.
Please repair the master to repair the door, the master heard this "click" sound, it means that this is caused by the loose belt drive. The processing method is to loosen the fastening screw of the motor base, rotate the motor away from the wave wheel axis, tighten the transmission belt tightly, and tighten the fastening screw of the base.
The noise value of the washing machine after maintenance is 49.7 dB
Before leaving, the master still did not forget to teach Xiao Bian a few tricks: If the washing machine issued a "bang" sound, this is generally an unbalanced washing machine causing a collision between the laundry tub and the shell, which requires us to adjust the center of gravity of the washing machine . If the washing machine pulsates when the pulsator rotates, you can try to put clean water on the clothes and check it. If there is still sound, this is mostly caused by the looseness of the pulsator screw. The pulsator can be disassembled and added at the bottom of the shaft. Pad gaskets of appropriate thickness to increase the clearance between the pulsator and the bottom of the bucket.
Range hoods also add to the fun
Xiao Bian home range hood
Xiao Bian, like everyone else, is equipped with a range hood to remove the kitchen fumes. However, when Xiao Bian’s home hood was working, it was obviously a very strenuous “banging†sound. What is this?
Noise level reached 58.8 dB
To this end Xiao Bian specifically asked a maintenance master, the master said that due to the working sound of the hood is not small, so because of the noise caused by some kind of failure is also very easy to be ignored by the user. In general, the noise emitted by the cooker hood can be found mainly from the impeller and the non-return valve.
impeller
On the one hand, the use of a range hood for a long period of time while the user neglects to clean it will cause the impeller to rotate normally and the resistance will lead to abnormal noises. In addition, some users will disassemble the impeller for cleaning, resulting in deformation of the impeller, imbalance of the impeller, or failure of the impeller to be installed. In place, it does not cooperate with the motor shaft and generates noise. In this regard, we can check if the impeller is improperly installed. If it is found to be improperly installed, it should be re-assembled and the impeller should be aligned and tightened.
Check valve
On the other hand, the regular hood will have a non-return valve. If the non-return valve is damaged, or the non-return valve is not installed, it will cause relatively loud noise. Therefore, we also need to check the non-return valve.
After repair, the noise level of the hood is reduced to 46.3 dB
There is a common possibility that the range hood is exposed to loud noises. The excessive wear of the bearings leads to the lack of lubrication. We can clean the bearings and add the appropriate amount of lubricant. Here, Xiao Bian also recommends to all users that the range hoods are best cleaned once every two months. Before the oil cups are not full, the waste oil in the oil cups is drained and the oil cups are cleaned.
Household appliances noise reduction need to keep in mind:
1, home appliances placed separately, try not to set the household appliances in a room, refrigerators such higher sound pressure levels should be placed farther away from the bedroom;
2, home appliance failures are eliminated in a timely manner, "sick work" of home appliances will be louder and less coordinated than the normal work, so once a fault is found, it must be promptly eliminated;
3, appliances staggered use, try to avoid the use of a variety of home appliances at the same time, to prevent noise superposition damage hearing;
4, home living room can raise more potted plants, help to absorb and evacuation part of the noise;
5, for a refrigerator with a higher sound pressure level of electrical appliances, without affecting the normal use of the premise, can be on the refrigerator back wall with sound-absorbing pads.
The full text of the summary: home appliances noise in ordinary times is better, but if it appears in the rest period, it is a disaster-level threat, and then, home appliances noise also implies hidden failures and security risks, therefore, to thinkæª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª æª
We engineer loudspeaker solutions that offer great durability, quality sound, and peak performance. When an electrical signal is applied to the voice coil it generates a magnetic field. The voice coil and magnets within the Speaker interact causing the coil and attached cone to move, generating sound. Our loudspeakers incorporate large magnets and particular voice coils to handle a broad range of frequencies and sounds. Additionally, our loudspeakers can be configured in multiple cone materials, sizes, shapes and gaskets to adapt to different operational environments. We have provided loudspeaker solutions for both indoor and outdoor applications. Our loudspeaker designs can be found in home theater systems and on the handlebars of some of the most exquisite motorcycles.
