What to do if the toilet exhaust is loud?

Generally, in order to prevent excessive odor in the bathroom, various methods will be taken to exhaust gases, so the exhaust fan is very important. The toilet exhaust fan will have a troublesome problem, that is, the bathroom exhaust fan will be relatively noisy. So what is the reason for the noise of the bathroom exhaust fan, and how to solve the problem of bathroom exhaust fan noise, the following is an introduction to this aspect.

Step Method.

First of all, the exhaust fan must be installed firmly, not installed in an unfixed place, which will greatly reduce the noise; Secondly, you should regularly lubricate the inside of the exhaust fan.

Check first to see if the ceiling is securely installed. See if it's a suspended ceiling and an exhaust fan.

It produces a relatively large resonance, and first makes the connection between the exhaust fan and the ceiling more firm.

To reinforce the ceiling. If there is noise, it must be vibrating, check ** or loose, if necessary, you can pad a high-density sponge sheet, and the noise should be smaller.

The vibration sound of the bathroom exhaust fan needs to be solved according to the actual situation, one is that the exhaust fan is transferred to the bathroom ceiling, indicating that the ceiling material is too soft or the material is fine, you can re-add two coarse materials, and fix the exhaust fan separately. First, the installation of the exhaust fan is unreasonable, or the fixing is incorrect, resulting in some exhaust fans.

There may be several reasons why the exhaust fan in the bathroom becomes smaller when it is turned on.

1.Aging of fan motors: The motors of bathroom exhaust fans may have aging problems after a long period of use. The aging of the motor causes a decrease in rotational speed, which reduces the exhaust airflow. In this case, it is recommended to replace the motor with a new one to solve the problem.

2.Blockage of fan blades: Dust, dirt and other rock debris may accumulate on the blades of the exhaust fan, causing the fan to be blocked when running, resulting in a decrease in exhaust airflow. Cleaning the fan blades regularly and keeping the ventilation smooth can solve this problem.

3.Blocked air ducts: Toilet ducts can be blocked by foreign objects or building materials, obstructing air circulation. In this case, the air duct needs to be checked and cleaned to ensure that the exhaust air is unobstructed.

4.Faulty fan switch: If the switch of the exhaust fan fails, it may cause the fan to not function properly or to slow down. Check whether the switch is damaged and repair or replace it in time.

To better understand the problem, here's a diagram:

To sum up, the reasons why the bathroom exhaust fan becomes smaller when it is turned on may include aging motors, clogged blades, blocked air ducts, and faulty switches. Depending on the specific situation, take appropriate measures to fix the problem, and the normal exhaust effect can be restored.

1. Closed toilet exhaust method 1: install exhaust fan.

Installing an exhaust fan is one of the most effective ways to solve the problem of ventilation and exhaust. However, the exhaust fan should be selected according to the size of the bathroom, choose the appropriate power, choose the motor working sound is small, and leave the air inlet for the bathroom when making the exhaust fan for the eggplant, that is to say, the door of the bathroom should be slightly opened, and the baby should not be closed too tightly, otherwise the exhaust effect is not good.

Precautions for exhaust fan installation: Check whether the exhaust fan has sufficient strength and whether the fixing screws meet the size of the fan mounting hole. Check whether the frame and fan blade are deformed, whether the fan blade rotates flexibly, whether there is friction, and check whether all fasteners are complete and tightened.

Check whether the position and installation size of the air inlet and outlet are opposite.

2. Closed toilet exhaust method 2: safety ventilation device.

In addition to the exhaust fan, there is also a ventilation device that can be installed, and many bath bombs now have this function, and we consider adding this function when choosing a bath bomb. If you have the budget, consider installing a fresh air system. It operates in both directions, which can carry out full heat exchange between indoor and outdoor air, which can meet the ventilation needs of cold weather; It can also purify indoor air and effectively remove gaseous pollutants.

There are two reasons for this, the first is because the screws are loose and the second is that the fan is too dusty. You can take it apart and take a look.

Remove the back cover screws first, and remove the back cover.

The back is glued with double-sided tape, so find a place where you can start and slowly open it.

After the keyboard is opened, there are still a few wires in the back, remove and classify them, confirm that all the screws are finished, and the dismantling board should be on.

After the C shell is removed, the silk on the motherboard is removed, and the wire on the motherboard will generally have a triangular arrow, so it will not be wrong, and the motherboard will be removed.

Then it's time to get the screws on the motherboard that hold the CPU fan heatsink in place! Remove the radiator and fan after removing the screws.

Generally, there are screws on the fan that can be opened, and then we remove the screws on the fan, disassemble the fan, and remove the dust from the fan.

Clean the fan, replace it with new silicone, and add some lubricating oil.

Then just follow the steps of the reverse process when dismantling and put it back on.

Finally, it is time to call it a day and test the machine.
