What to do if the kitchen often smells the neighbor s cooking

This is not a problem with the range hood. The range hood is equipped with a check valve above the machine to prevent the oil fume from backfilling. Your kitchen often smells your neighbors cooking, so you can check the flexibility of the check valve through the machine inlet.

The inspection method is: after turning off the power for a few seconds, the check valve will automatically fall, if you can't see it, you can listen carefully to see if there is a "click" sound of the check valve falling, if the check valve is not flexible and can not fall, it means that it has been stuck with oil and needs to be cleaned. The method of cleaning is to remove the exhaust pipe from the check valve seat, bend the check valve piece by hand, wipe the check valve plate and valve seat with cleaning agent and rag, and install it on the shaft hole.

The check valve was troubleshooting, and the problem of oil smoke backing up and smelling was solved.

In addition, it is also common for the air outlet pipe joint to leak, the gap around the air outlet pipe inserted into the flue mouth is too large, the connection and installation with the common flue are not standardized, and the air outlet pipe falls off from the flue mouth. If the above phenomenon occurs, the check valve of the range hood will lose its effect, it is recommended that you check whether the air outlet pipe is normal, and take measures to plug the air leakage.
