Home appliance accessories installation notes how to repair home appliances

The installation and use of home appliances is inseparable from the accessories. The accessories play an important role in the use of home appliances. It also determines whether people can use the appliances safely, efficiently and conveniently. What are the precautions for the installation of home appliances? The accessories of a home appliance are broken. After that, I need to be able to repair it, how to repair home appliances?

First, home appliance accessories installation notes

1, can not be operated

In order to prevent electric shock and protect personal safety, the installation operation of household electrical appliances must be carried out in the event of power failure, and cannot be operated with power. After installation, the test machine can be energized only after checking the problem. In addition to checking the relevant performance, the test machine should check whether the outer casing is charged. The electrical equipment with the outer casing can not be used. It must be repaired in time, otherwise electric shock will occur, affecting people. Life.

2, the voltage must be calculated

Before installing and using household appliances, you must carefully check whether the voltage (rated voltage) of the electrical equipment matches the power supply voltage. If it does not match, it will damage the electrical equipment and even cause more damage such as fire. If you need to install and use, you must use a suitable transformer. . The indoor power supply of residential buildings is 220V single-phase AC. One of the wires of the power supply is “phase line” (also called “fire line spoon, one is “zero line”), and Jiang has a grounding protection line. The power supply of household appliances is often The power socket of the household appliance shall be provided with a two-hole socket and the well shall be equipped with a two-pin plug. When the electrical equipment is installed, the switch shall be installed in the "fire line", otherwise the electrical equipment will be charged when the switch is disconnected.

3, plan the highest load of power supply

In recent years, due to the improvement of domestic water supply and the rapid development of the home appliance industry, the variety and quantity of household appliances have increased rapidly. Many households have a variety of household appliances, so that the phenomenon of line overload appears in a thousand. The power supply line of the household appliance is composed of a wire to connect the electric equipment, the power source, the control and the protection device, and the like.

The current load allowed by the power supply line is determined by the material and section of the wire. Commonly used wire materials are copper and aluminum. The copper wire allows a larger current than the aluminum wire. The larger the wire cross section, the larger the current allowed to pass. In order to ensure the safety of electricity and ensure the normal performance of electrical equipment, each household appliance should have a separate power outlet to supply power. It is not allowed to share a multi-head socket with several electrical equipment to avoid overloading the line and affecting the performance of the electrical equipment.

4, understand the maximum current

Before installing electrical equipment, it is necessary to know whether the safe current carrying capacity of the power supply line can meet the requirements for use, that is, the current carrying capacity of the power supply line conductor is not less than the operating current of the power supply equipment. The operating current of a single-phase AC 220V consumer can be estimated by dividing its rated power by 220V.

5, safety first

In order to ensure the safety of the power supply line, a wire is installed at the knife switch in the distribution box. When the line current is too large, the wire is broken to cut off the power supply, to avoid accidents, and to protect the safety of the line and the electrical equipment. The specification of the wire must meet the requirements of line protection, and it should not be increased casually, and it can not be replaced by other wires. In order to ensure the safety of electricity, it is better to install the leakage protection switch at the household end.

Water purifier maintenance

Water purifiers are kitchen appliances with very high usage rates. Regular cleaning can remove stain residues, not only can effectively reduce the cost of use, but also enjoy a better clean water life. When using the water purifier, pay attention to avoid direct sunlight. Strong and long-lasting sunlight can cause the water to overheat, and the overheated ambient temperature will give some microorganisms a good living space, which can easily cause bacterial infection. At the same time, avoid close to the heat source, which will affect the life of plastic parts.

Drinking machine maintenance

Do not move the water dispenser directly after installation. If the water quality becomes turbid after using for a period of time, it is best to stop using it and continue to use it after cleaning the filter. There are multi-stage filter elements and permeable membranes in the straight drinking fountains. The life spans of the filter elements and permeable membranes are different. The filter has a service life of 3-12 months, while the permeable membrane has a service life of 1-2 years. If the water quality is not good and there is no improvement after cleaning the filter element or the permeable membrane, the filter element and the permeable membrane need to be replaced.

Water machine maintenance

The water purifier should be cleaned and maintained regularly to extend the life of the water purifier. Usually, if it is not used for a long time (such as more than 1 month), it needs to be taken out and immersed in the disinfectant to avoid the breeding of bacteria. However, the process is troublesome. It is recommended that even if it is not used, it is often turned on with a small amount of water to allow the inside of the machine. The water forms a circulation, minimizing the deposition time of the stagnant water. In addition, the activated carbon filter of the pure water machine usually needs to be replaced in about one year.

Electric kettle maintenance

Electric kettle is the most common small household appliance. Do not use electric kettle to cook things with acid, alkali and salt. When using it, you must first install water. After powering on, the water should be higher than the heater but not above the highest water level. It must be taken care of during the boiling process and placed out of reach of children. When not in use, place it in a dry place. After using the kettle for a period of time, the scale inside the kettle should be removed, otherwise the life of the heater will be greatly affected.

Precautions for the installation of home appliance parts As above, when you need to install the home appliance parts, you can look at the specific instructions of the home appliance. If you don't know how to install the home appliance parts, it is best not to install them. How to repair home appliance parts? It is not easy to repair home appliance accessories. It is not easy to repair home appliance parts. It is best not to repair them. Look for a special person to repair.
