As the weather gets warmer, we are about to enter the spring and summer. Household appliances that have experienced a whole winter will welcome the baptism of hot and cold exchange. Do you consider making a comprehensive inspection and maintenance of your home's electrical products based on seasonal changes? Especially for water heaters, the frequency of bathing will increase significantly after entering the spring and summer.
Gas water heater maintenance is in daily life
Frequently check the gas pipeline for aging, rupture, damage, etc. Once found, it must be handled in a timely manner, and do a good job of gas leakage prevention. The water filter of the cold water inlet is cleaned daily. If the water filter is blocked, the water heater will not work properly.
Always observe the flame condition. If it is found that the flame is abnormal, such as yellow flame and black smoke, stop using it immediately and notify the maintenance department for treatment. Entrust qualified professionals to check the heat exchanger and burner for carbon deposits and blockages every six months, and clean them in time to ensure the normal operation of the water heater. Always observe whether there is water leakage.
Electric water heater scale cleaning is flawed
When the water heater is in normal use, replace the thermostat and heater every three years at the designated service point. When the amount of water in the shower is reduced, it is necessary to clean up the clogged debris in time to ensure that the outlet is unobstructed. Do not replace the parts on the water heater yourself.
After the electric water heater is used for a certain period of time, a large amount of scale will be formed inside. When the scale is thickened to a certain extent, not only the heating time is prolonged, but also the cracking occurs, the inner tank has some damage, the heating time is prolonged, and the hot water output is increased. cut back. Electric water heaters do not have a drain valve and require professional cleaning.
The inner tank should be cleaned once in the season. The cleaning method is to first cut off the power supply, close the inlet valve, and then open the outlet valve to reverse the plastic drain on the safety valve counterclockwise by 90 degrees to naturally drain the water from the water heater. Precipitate. Then, wash the tap water again, wash it, and then return the drain ear to the original position. Note that it can be energized after filling. Users who do not turn off the water heater power supply all the year round should always care whether the water heater is normal. If there is any abnormal situation, it should be sent to the maintenance point for maintenance.
Hood season maintenance instructions
The most troublesome thing to clean up at home is the cleaning of the range hood, which is not only greasy, but also difficult to clean. However, if you do not clean the range hood for a long time, it will cause the following hidden dangers:
First, the oil circuit is blocked, and then the waste oil is accumulated, the motor load is aggravated, and the motor is burnt out in severe cases;
Second, there is no sealing and reset after cleaning the device, and oil leakage occurs;
3. When the hood is cleaned, the balance of the exhaust turbine is destroyed, causing jitter and friction;
4. Because the flue is narrow or the exhaust pipe is too long, the suction is large and the displacement is small. The two are not proportional. In this way, the accumulated airflow in the wind warehouse is intensified, causing the whole machine to shake. loud voice.
5. If the hood with circuit board control is improperly cleaned, the circuit board will be short-circuited by moisture and cause control failure.
Our advice to you is:
1. As long as the oil hood is dredged as little as possible, if it is to be cleaned, it requires professional operation;
2. Do not wipe the hood switch with a damp rag and a slip agent. If the switch is slow and slow, it will burn the motor.
3. If it is a European-style range hood, you only need to clean the oil filter net below frequently. It is not necessary to assemble the whole machine within three years.
Hotel / hotel hotel large range hood regular cleaning three major points:
First of all, the regular cleaning of the exhaust fan of the large range hood can improve the exhaust effect, because the chisel turbine blade of the large fan has a small gap, and once it is full of greasy smoke, the effect will be greatly reduced.
Secondly, the lampblack purifier should also be cleaned regularly. The lampblack purifier is an important part of the smoke exhaust system and concentrates on the most oily places. The cleansing of the purifier not only facilitates the smooth discharge of smoke in the kitchen, but also eliminates fire hazards.
Again, the main pipe of the exhaust pipe, especially the low level of the main exhaust pipe, is the place where the soot is accumulated.
Finally, I hope that our suggestions can provide the necessary help to the majority of users.
Gas stove season maintenance instructions
The first is to adjust the damper. All gas cookers must pay attention to adjusting the size of the flame and the damper, so that the burning flame is blue cone, the flame is stable; because the damper is too large, the amount of air is too much, the fire is not easy to point; the damper is too small, easy to produce red fire and incomplete combustion . For a gas stove with a flameout protection device, the damper adjustment ratio is as follows: one damper that directly connects the small burner head should be closed as small as possible, and the other vent door that opens to the outer ring can open one third of the fan surface.
The second is correct ignition. When the gas cooker with the flameout protection device is ignited, press the button, and when the switch is turned on, it cannot be released immediately. At least the switch must be pressed for 3 seconds to release. Because there is a thermocouple in the small burner part of this type of cooker, it needs to be preheated before the magnetic valve can be tightly sucked, and then the gas path is opened. Otherwise, the air path will be automatically cut off.
The third is regular maintenance. Care for the cooker, keep the cooktop clean, the fire hole on the burner is easily blocked by porridge, vegetable soup, medicinal juice, dust and other dirt. It should be decontaminated at any time, wipe off the water stains, and regularly use a small wire to dredge the stove on the stove. Vent holes to prevent clogging. The thermocouple should be sanded regularly with fine sand, and the oxides deposited on the thermocouple or the heat transfer-resistant stains should be removed to keep the cooker clean and the gas unblocked and maintain its good heat.
The fourth is to check frequently. Always check the sealing performance of the plug valve (the valve at the metal pipe and the rubber pipe joint), and oil it in time; often check the coupling hose for cracking and aging, and replace the new hose when problems are found; after burning for a long time, the temperature of the cooker Higher, to prevent dripping of cooling water, so as not to let the cooktop peel off.
Refrigerator season maintenance instructions
Many users may have such an approach. In order to save electricity bills, the refrigerator is often turned off when the weather is cold. So, is this practice appropriate and will have any adverse effects on the refrigerator?
In this regard, the refrigerator maintenance engineer Mr. Su suggested that some users may cut off the power supply of the refrigerator in winter. If the refrigerator is stopped for a long time, the refrigerant will solidify in one place, and the refrigeration tube is easily corroded, especially for those who have used for five or six years. The above refrigerators, if not properly maintained, may cause a malfunction in the spring of the following year.
Mr. Su introduced that in addition to this, the usual cleaning work is also very important. It is recommended to clean the refrigerator regularly for two or three months. Under normal circumstances, after the refrigerator is used for a period of time, the internal accessories will accumulate a lot of dirt, especially in summer, so the accessories should be removed and cleaned with water or salt water; the surface of the electrical parts and the surface of the refrigerator can be wiped with a dry cloth; the condenser on the back It is easy to accumulate dust and affect heat dissipation. Use a tweezers or a vacuum cleaner to clean it.
