Several risks of not cleaning solar for a long time;
1. The thermal conductivity of scale is much lower than that of metal. The thermal conductivity of steel pipes is 6 to 1,000 times higher. tartar; scale in vacuum tubes will cause serious problems. Affects hot water temperature; hard scale can reduce the thermal energy conversion rate of solar energy or even fail. This is the reason why the water temperature of solar water heaters decreases and the water supply decreases.
2. Scale contains a variety of chemical components and the accumulation of harmful substances in the water can increase. lead to skin allergies.
p>3. Sludge, microorganisms and bacteria also generate many harmful substances during their continuous renewal and alternating reactions over a long period of time. This can provocate various skin diseases. Some women and children sometimes experience itching and red spots on the skin after taking a bath.
Scale has the following five major damages to solar energy:
(1) The heat collection efficiency decreases and the thermal conductivity of scale does not reach 1% of that of metal. The heat transfer of the heat collecting tube is extremely slow, and the temperature of the hot water is low; the heat collecting tube cannot be removed in time after absorbing heat, and the coating is easy to overheat, which affects the life of the vacuum tube. ;
(2) The probe sensor is prone to malfunction and the water level detection signal Distortion, poor heat transfer of electric heating tubes, explosive tubes;
(3), hot water is cloudy and impure, and the scale contains a small amount of "nitrates and nitrites", which are toxic and harmful to the human body (causing cancer)), the so-called "thousands of boiling water are toxic and cannot be drunk". Tartar is a breeding ground for the reproduction and growth of bacteria. Hot water contains a large number of bacteria that can cause allergies in the human body
(4) It is easy to corrode Once scale accumulates. in the water tank, it is easy to cause corrosion under the scale and the water tank is easy to rot and leak. Therefore: for the health of you and your family and for the protection of your skin. , please clean the water heater and the waste and scale in the water tap in time

p>
3. Automatically heat for 20-30 minutes afin that the descaling agent solution comes into complete contact with all parts
4. Open; draining and drain the cleaning fluid;
5. Fill the water tank with water then circulate it for two minutes;
6. Drain circulating water, as well as cleaning and descaling. the work is completed.
Warm reminder:
1. Different solar water heaters have different structures. Please adjust the use according to the instructions (it is recommended to be used by professional maintenance personnel).
2. Heat the water to around 40 degrees for better descaling effect.
3. Clean the solar water heater every three months to ensure that it is in good working condition. If it has not been cleaned for more than twelve months, please increase the dosage.
4. If it touches sensitive parts such as eyes, nose, etc., please rinse it with water.au clair.
Technology for cleaning household appliances
Washing The door of the machine cannot be opened.
p>Due to the principle of washing machine operation, the door has a safety lock function. If the device is turned on, the washing machine lid cannot be opened. , when the drum washing machine door cannot be opened, it is best to simply turn off the main power and try to turn it back on later.
There is a PTC heating element inside the washing machine. When the door is closed, the PTC element heats up, causing the bimetallic sheet to bend from the heat, turns on the main power and locks. the washing machine door at the same time. After a while after power off, the bimetallic part cools down and automatically resets and unlocks. If the PTC heats up
The door of the machinee washing machine cannot be opened. Here are some easy ways to fix this problem
If the component is damaged, the washing machine door. the washing machine cannot be opened. At this time, keep the power off, press the door cover handle with your hand, and rely on the vibration to reset the plastic pin. You can then open the door and then call a repairman.
If the door still cannot be opened for a long time after the washer switch knob has been turned to the off position, you can turn the knob again in n Any position and you will hear the door lock "pop" after a few seconds. sounds, the door can be opened at this time.
As there are also electronic circuits in the washing machine, some faults are similar to computer failures. Simply turn off the power, leave itremaining electricity (capacity) in the circuit will discharge later, then plug it in. Power supply, the circuit can be restored to the default value.
If the above efforts are ineffective, then you need to manually open the washing machine door. Usually, there is a hidden emergency maintenance door on the lower right side of the washing machine. Use a screwdriver. insert it into the slot that extends above the door and carefully remove it. The emergency maintenance door can be opened by gently lifting it.
After opening it, you can see two things (different brands of devices may be different), one is the pull cord and the other is the rotary switch.
Here are some easy ways to fix the problem of washing machine door not opening
There is a pull cord on the side left of this model (some models do If you don't havethis cord), pull. After opening, gently pull to open the locked washing machine door.
The last tip: the right knob can be rotated. As long as it is turned 90 degrees, the accumulated water at the bottom of the drainage can be opened (note that the accumulated water rushes outward). . After the accumulated water is drained, the quilt can be opened. The washing machine door is locked.
General washing machines are equipped with electric door lock protection devices. The washing machine is still in protection period within two or three minutes after power failure and the door lock does not open. So don't do it after the washing machine stops working, open the door quickly, and then open it after the protection period is over.
Home appliance cleaning technology includes air conditioning cleaning technology (sus unitshanging, cabinet units, cylindrical cabinet units, ceiling units, coil fans, outdoor units, etc.), range hood cleaning technology (Chinese style, European style, side suction type, built-in cooker, etc.), water heater cleaning technology (electricity, gas, solar energy, air energy, etc.), washing machine cleaning technology (pulsator, drum).
For skills in cleaning household appliances, you can go to a housekeeping training center, because there are many household appliances to clean: water dispensers, hoods kitchen, air conditioners, induction cookers, refrigerators, computers, televisions and other frequently used household appliances. Electrical appliances have different cleaning methods. Some need to clean the interior, while others only need to use cleaning products to cleanCoat the exterior according to the instructions.
Appliance cleaning is still a new industry and the market is still empty. Professional appliance cleaning companies began to appear first and foremost. second-tier cities, so it is necessary to find a good appliance cleaning training company in the right city.
The scope of cleaning household appliances. Generally speaking, so-called appliance cleaning mainly involves cleaning commonly used household appliances such as kitchen hoods, air conditioners, washing machines, water heaters, refrigerators and water dispensers. In principle, every home has these items, but not all of them may be available. Yes, but at least one or a few of them.
Cleaning the kitchen hood:
Irregular cleaning of the kitchen hood will lead to poor discharge of toxic fumes, increase the dispersion rate and increase damage A. A large and fresh home environment is the main concern of families modern 21st century.
After the hood has been used for a period of time, for example three months, a large amount of oil will stick to the impeller and flue, increasing the weight of the impeller and , from a physical point of view. from one point of view, increases the moment of inertia. The motor starting current increases, the load increases, the motor loss increases, and the noise also increases.
Oil stains accumulate for a long time and oxidize to form acidic substances that corrode and rust the range hood. Hydrocarbon pollution accumulated inside the hood and flue over a long period of time will also causes fire risks. Oil on the turbine duct increases viscosity and makes the exhaust less smooth.
