The first patent for machine dishwashing appeared in 185, which was owned by Joel Houghton. He invented a manual dishwasher.
In p>1929, the German company Miele made the first electric household dishwasher in Europe, but its appearance was still a simple "machine" and it was not closely related to the overall family environment.
In p>1954, GE Company of the United States produced the first electric desktop dishwasher, which not only improved the washing performance, but also improved the overall volume and appearance.
Japan was the first country to engage in the research of dishwashers in Asia. By the middle and late 199s, Japan had developed a microcomputer-based fully automatic desktop dishwasher.
At the same time, Europe and America have developed household dishwashers into kitchen appliances with a unified image.
Dishwashers are classified by different names from different angles, and there are usually the following categories:
According to use, they are divided into commercial dishwashers and household dishwashers.
1. Commercial dishwashers are suitable for commercial use, generally used in hotels, restaurants, restaurants, etc., and are characterized by high temperature, disinfection, high intensity and short time treatment. There are conveyor dishwashers, flying-in dishwashers, door dishwashers (also known as lid-lifting or lid-lifting) and desktop dishwashers;
2. Household dishwashers are only suitable for families, mainly including cabinet type, desktop type and sink integrated type. Desktop dishwashers are minicomputers, and the washing capacity generally does not exceed 5 sets. Cabinet dishwashers are divided into 45CM and 6CM cabinets, and the washing capacity is divided into 8 sets and 12 sets. The sink dishwasher integrates the functions of sink and dishwasher, with the same size as the sink, and the washing capacity is 6 sets.
according to the structure, it can be divided into household dishwashers, desktop dishwashers, cabinet dishwashers and integrated sinks.
3. The desktop dishwasher is compact, occupies small space, has small capacity and is flexible to place.
4. The cabinet dishwasher has standardized dimensions and large capacity, and is suitable for matching with the whole kitchen.
5. The integrated size of the sink is the same as that of the sink, and it is small in size, and it is not necessary to change water to electricity for installation, so it is suitable for China kitchen.
according to control mode: it is divided into electromechanical control and electronic control.
5. electromechanical control is a more traditional control mode, and the core control device is electromechanical program controller, which has stable and reliable performance.
6. Electronic control is based on single-chip microcomputer, which is more flexible in program design and shows various working states, and is increasingly favored by people.
according to the installation method: it is divided into free-standing and embedded.
7. The embedded installation is integrated with the kitchen cabinet.
8. Freestyle random placement
According to the washing method, it can be divided into spray type and vortex type.
9. Spray type is to spray high-pressure water up and down, left and right to achieve cleaning effect. 1. Vortex is common in household dishwashers and ultrasonic dishwashers.
according to the transmission mode, it can be divided into uncovering type, basket transmission type, oblique insertion type and flat mesh belt type.
11. Uncover type: It is commonly used in household dishwashers. Due to the limitation of washing capacity and washing speed, commercial dishwashers are less and less used in commercial dishwashers.
12. Blue transmission type: it is commonly used in commercial dishwashers. Because of its relatively low investment cost and relatively troublesome operation (different washing baskets need to be designed according to different tableware, but it is more difficult to clean irregular tableware), restaurants, canteens and restaurants have gradually faded out of this market because of poor feedback from customers, and it is only widely used in five sets of tableware disinfection and distribution companies.
13. Oblique plug-in type: it is often used in commercial dishwashers, and the market has different reactions. However, there is a dead angle for cleaning larger tableware and plates, and they should not be placed too closely.
14. net belt flat type: it is commonly used in commercial dishwashers, also known as the fourth generation commercial dishwashers, and the market response is good. It has a good cleaning effect on tableware with a width of not more than 76 cm and a height of not more than 55 cm, and the cleaning speed is slightly different due to the shape and size of tableware. Therefore, it is the best choice for restaurants, canteens and restaurants, and represents the most advanced technology of commercial dishwashers.
