Dishwasher was born in Europe and the United States. 1929 Germany Miller (Miele) company to create the world's first electric household dishwasher, but the shape is more simple "machines" did not have the family and close contact with the environment. GE in 1954 the United States produced the first electric desktop dishwashers, washing performance not only improved volume and shape complete machine has also improved. Miller company in 1978 to create the world's first microcomputer-controlled dishwashers, people more closely related to machine, dishwasher and home have been better reflected more and more into the dishwasher Western families.
In Asia, in the dishwasher the first study in Japan, the last century to the late 1990s, Japan has developed a desktop microcomputer automatic dishwashers, the representative of the enterprises Panasonic, Sanyo, Mitsubishi and Toshiba.
Dishwashers classification
Dishwashers one of a number of different by structure type can be divided into the floor-, portable, tank-type, embedded Tibetan.
According to distinguish between open device can be divided into pre-open and open-top two. Former open-door is open, they can pull the same desk as each frame, tableware very convenient to take, and not because of its open top, back to the users with more use of space. Top-compared with, it is not convenient to take tableware, and the top can not fully utilized.
Washed by the way, can be divided into impeller, Jet, and ultrasonic-leaching-such as four kinds. At present more commonly used for the impeller and Jet, the two forms of dishwasher detergent is simple in structure, the result is better, and is easier to maintain low price advantages.
In recent years, the market has emerged automatic dishwashers and automatic dishwasher. They are dissolved by water detergent to be fired at high speed cleaning dishes, utensils, washing automatically after drainage, and water purification for further processing, the final use of their own or from the waste heat of the electric heating elements dishes will be hot air dryer. The difference is that, automatic dishwasher through the electromagnetic injection into the valve control, and the influent automatic dishwashers, washing, heating and drainage procedures, such as by the controller.
My dishwasher slow development rate less than 1%
China's dishwasher production late start in the 1970s began work on the development dishwashers, dishwasher production in the first with the Hubei Yichang dishwasher manufacturing company, Ningbo washing machine factory, Beijing things mechanical trouble, but output are not. With Aokema, Little Swan, the United States and joined the Haier, China's dishwasher production and quality has greatly improved, but it has been in a very awkward situation could not have developed by leaps and bounds. According to industry sources, the reasons for this situation is more complicated.
The first is the high price. Because of its technological level and advance into higher, and domestic enterprises do not have a dishwasher production of a sufficient size of the market, leading to a dishwasher prices high.
This was followed by the washing long time, the power consumption. Dishwashers have to go through a two-wash three disinfection processes in a bowl to wash over one hour. Dishwashers power from 950 watts to 2,300 watts ranging from washing down to a bowl of a unit of electricity, coupled with the erosion of the water several times a month down to spend can not be discounted.
The third is the design defects. Dishwasher the first born in Europe and the United States, Western tableware mainly to the plate, dishwasher was tailored to the plate. China and cutlery in the bowl, cans, pots, and so fundamentally not apply dishwashers, water erosion difficult to wash utensils China.
Fourth, China's limited housing conditions, generally small kitchen area, an open space to the dishwasher is not vacated, and dishwashers are on the water requirements, which limit dishwasher ordinary families.
In the United States, Germany, France and other Western countries, dishwashers current penetration rate has reached 60 percent to 70 percent, and less than 1 percent in China, dishwasher market potential is still very great.
How to choose the right dishwasher
Under normal circumstances, we should first consider choosing the type of dishwashers and specifications. Nozzles can usually choose-or impeller models. In accordance with their respective specifications can be the size of the family to determine how much, if three people around the family, choose specifications in the 700 watts to 900 watts of dishwashers to meet the day-to-day use.
Because the function of dishwashers more, as long as the average family with a wash, rinse, dry and automatic process control functions on it. At the same time also have the option of rapid washing, Chong, rinse and spin Fenshua functions such as dishwashers, the advantages of such models is washed clean, safe, reliable, and can automatically cycle, but prices should be relatively expensive. Also, in recent years the market has also launched a microcomputer control
System, pulsating bubble flow, double rotating spray arm, the sensors detect features such as dishwashers, consumers should be able to choose their own hobbies.
In addition, the appearance of dishwashers and quality in particular can not be overlooked. Look dishwashers depend on the aesthetic appearance generous, shell Qiceng whether uniform, smooth smooth, elastic doors deduction is appropriate, in jail
Solid and reliable, bowls basket whether the welding firm, and at the bottom of the wheel is flexible, and pulled out a bowl of baskets in the process, whether card hysteresis phenomenon. Oxfam hands moving programmed, controlled request for the operation process of smooth uniform. Switches should be flexible and reliable. At the same time, should also be carefully examined for the spray arm, and so it is a quality components. Power started in the connected machines, the performance of the insulation is particularly important, we must ensure that no leakage phenomenon, the operation of pumps and motors flexible, small vibration, low noise, speed and stability. The various features of dishwashers on-off button to easily contact good, strong water spray uniformity, and washing utensils should be clean to clean. If meeting these requirements, then one will be able to purchase the satisfaction of the dishwasher.
Ultrasonic washing utensils in the dishwasher to bring the Gospel
Ultrasonic dishwashers use of ultrasonic cleaning is the principle: When the ultrasonic liquid medium, will be very high frequency vibration suppression liquid medium, the liquid molecules produced by the wave of alternating positive and negative. When the sound intensity reaches a certain value, the rapid growth of small liquid cavitation bubbles and instantaneous closed strongly, strongly micro-explosion and shock wave to the surface being cleaned of the dirt has been damaged, and from the cleaning surface piece. Although each of the air bubble is not the role, but there are per second on 100 million cavitation bubbles in the role, a good cleaning effect. Because ultrasound can penetrate solid material而使the liquid medium vibration and produce cavitation bubbles, this method does not exist cleansing wash less than a corner, and the industry that ultrasonic cleaning cleansing high.
Compared with the traditional dishwashers, ultrasonic dishwasher also has the following advantages:
1, power-saving, water-saving and noise. Because ultrasonic dishwashers do not need motors, pumps, high-pressure washing is not required when water, recycled water, and do not need the Rotary movement, everything to the vibration of water molecules quietly completed, machine noise, and water-saving, energy saving.
2, simple structure, long service life. As used in the ultrasonic vibration of water molecules have to wash dishes, dishwashers do not require the traditional rotary spray arm, stirred water impeller agencies, does not need more pumps, motors, the circulating water system, therefore the structure much simpler produce Fault far fewer opportunities, simple maintenance and after-sales service.
3, without using special detergents. Relying mainly on traditional dishwasher detergent for cleaning chemicals, and the ultrasonic dishwasher detergent in principle, no. Join degreasing detergent also play a supporting role, detergent without special requirements.
The advent of ultrasonic dishwasher, it will completely solve the problem of washing dishes, for the Chinese and overseas markets dishwashers infinite vitality.
Use
1, the use of dishwashers, we must connect earth to ensure safety. Dishwasher is not completely replace manual labor, and therefore must not be washing utensils in the entrainment other debris, such as fish bones, leftovers, such as rice, debris filter easily plug nozzle rotation or prejudice influence washing effect.
2, to the putting of cutlery, tableware, should not be exposed metal basket. Relatively small cups, tablespoons and other apparatus to avoid falling and prevent collisions, to avoid fragmentation. If necessary, the use of more precise small basket containing these small appliances, it would more secure.
3, in order to better wash utensils, eliminate water spots should be used for the dishwasher detergent to wash dishes, but not be used to replace the soapy water or detergent. Special detergent is characterized by low-foam, high-alkaline, it is not the direct use of hand washing to prevent skin burns.
4, drying utensils in the dishwasher when consumption of large amounts of electricity, if not anxious to immediate use, as far as possible, should be cleaned and natural ventilation drying methods, and this may reduce the energy consumption.
5, higher than 70 ℃ not to use the water, so as to avoid plastics, rubber distortion or damage.
6, dishwasher operation, not to plug the vents, while not forced to move or impact dishwasher, in order to avoid failure.
7, washing finished, it is necessary to promptly clean filters accumulated dirt, released after the in-situ clean.
8, dishwasher machines must be kept clean to prevent the generation of smell. Clean, not its control switches, etc. by water Linta, insulation performance guarantee, so as to avoid leakage.
Aspects of the new dishwasher
Water-saving dishwashers. Matsushita Electric production of a water-saving dishwashers and achieve at least 12 L of water, but can be washed by the water adjustment of tableware, even a small amount of washing utensils in it does not waste water.
Disinfection functions have dishwashers. From atop the box with a sealed, wash barrels, and electrical control devices such as rotary nozzles composed of dishwashers, in the box at the end of the wall with an ozone air pump, are connected guided tracheal I. trachea through the washing barrels into its inner cavity wall, the tableware can be disinfected.
Energy-saving dishwashers. United States dishwasher manufacturers will be able to filter out the small food particles multi-filter combinations to improve the filtering of water into the dishwasher for re-cycle, and reduce insertion motor bathing pool size, lower bath pool The water demand. As dishwasher energy consumption of 80 percent for heating water, the water-saving energy conservation.
Cleaning can repeat the dishwasher. Japan Luokeshi Electric Company design and manufacture a new type of dishwasher, through high-temperature cleaning system to repeat, remove glued to the bowl with the food and greasy. This dishwasher at 65 ℃, the first bowl-again, and then cleaning agent in the same temperature washing second times. Users can also, according to the bowl texture, greasy and should be thoroughly cleansed of the choice of different temperature scrubbing.
Anhydrous dishwasher. Australia's university students invented a kind of dirty water can also clean the dishwasher cutlery. This dishwasher using "supercritical carbon dioxide" formation of a liquid, it can anhydrous circumstances easy to remove the oil-dish meal, and it does not require installation of drain pipes or placed in the drainage channel in the vicinity.
What should not be machine washable tableware
● groove with the teacups, bowls and plates inside the water can not be quickly evaporating, it will not completely drying, and should not use dishwasher cleaning.
● beautifully glazed tableware in general to maintain the color of durable, but frequent use of washing machines and the possible loss of crisp, it would be inappropriate often dishwasher cleaning.
● aluminum tableware products may fade, it is necessary to use fewer machine washable.
● silver tableware products contact with the sulfur-containing food ingredients (such as eggs, fruit, etc.) may have tarnished, can be used for preparation clean silverware is not the washing machine.
● handmade tableware products in the high water temperature and detergent environment would be harmed, not suitable for use dishwasher cleaning.
● plastic tableware is not high temperatures, easy deformation, heat-resistant plastic containers also can be placed only in the top basket dishwasher cleaning.
● crystal glass tableware products can be used dishwasher general cleaning, but after several laundered some transparency will deteriorate, thin and crisp, to the extent possible "minor" washing procedures.
Dishwashers should be regularly cleaned
Regularly with a soft damp cloth to clean the outer surface and dishwasher doors inside. Do not use rough or acid detergent. Clean with damp sponge door seal. Ceramic outer surface cleaning detergents can be used in general. Subject to the prior ensure that the electricity.
Regularly clean water filter interface. Close faucet, the water from the hose, fastening filters, gently rinse and re-installed on the hose.
Arm regular cleansing spray nozzle to avoid blockage. Spray arm easily demolished, just under its fixed fastening nut, unplugging the rinse water nozzle, then loaded back in situ.
Demolition filters regularly inspect and, if necessary, carry out clean. Gently press and hold the two stalk wing, anti-clockwise rotation out. Pushed out from underneath, and then removed from the base and became the filter. Brush brushing with filters, if filter blockage, dishwasher will not work. Ensure that the correct replacement and cleaning process to avoid damage to wash pump.
Common Faults and inspection methods
Fault 1: dishwasher yet to start.
Inspections: Plug Power has been correctly inserted into the socket, room, if there were, whether the doors are properly closed, the power switch is in the "on" state.
Fault 2: dishwasher not flooded.
Inspections: whether screw taps open water hose connection is correct, water pressure is adequate, and whether the water supply hose bending or folding into a non-blocking valve filter.
Fault 3: dishwasher not drainage. Inspections: whether drain bending or folding. Fault 4: dishes on the formation of calcium precipitation or produce tunica albuginea. Inspection: Salt whether the lid is closed, and bleaching agent is appropriate. |
