Description

Multifunctional Automatic Dishwasher

technical field

The utility model relates to a tableware washing device, specifically a dishwasher. The dishwasher integrates washing, drying and disinfection, has a simple structure and takes up little space, and is especially suitable for household use.

Background technique

Existing dishwashers on the market are mainly technology imported from abroad, with high-pressure water cleaning as the basic principle, and washing away the surface of dishes by water guns to play a decontamination effect. The requirements for the size and depth of dishes are high, the water consumption is large, and the decontamination ability is not ideal. The household ozone dishwasher is a new type of dishwasher that is designed with the ozone generating and adding device in the dishwasher. When the dishwasher washes the tableware, the ozone generator generates ozone, which is introduced into the water in the cleaning chamber through the catheter. Ozone is easily soluble in water, and the ozone water formed has strong surface sterilization and virus elimination characteristics for disinfection. However, the ozone generator of this kind of dishwasher has high manufacturing and operating costs, short life, and ozone decomposes in water. Fast, short duration of disinfection action, cannot remove persistent contamination. "Mobile dishwasher" simulates the process of manual hand washing, moving the dishes one by one, using a brush to wash the inside and outside, washing a bowl as soon as there is one, and only takes the time to wash one bowl. Most of the existing dishwashers only have one or both of the functions of cleaning, disinfection or drying, and some of them still need to manually press the button to realize the conversion of the two functions. At the same time, most of the existing dishwashers use a fixed dish rack and rely on high-pressure water sprayed from the nozzle for cleaning, which has poor cleaning effect and consumes a lot of water.

Water tank 2 is located in housing 1 and is installed on base plate 8 and is connected with all nozzles 7 by water pump 11 and water pipe 12, and water pump 11 is installed on base plate 8 by water pump bracket 13, and water tank 2 is provided with water inlet valve and drain valve. An ultraviolet lamp 5 for disinfection is provided on the wall of the inner shell 18 . Pallet 6 is provided with alignment pin, and bowl rack 3 is installed on the tray 6 by alignment pin, and tray 6 is connected with tray motor 15 by reduction gear 14, and tray motor 15 and reduction gear 14 are installed on the base plate 8 by support respectively. Driven by the tray motor 15, the tray 6 can drive the dish rack 3 to rotate. A filter screen 16 is provided in the inner shell 18, and the filter screen 16 is positioned under the tray 6. The bottom of the inner shell 18 is provided with a water outlet 17 that can filter water into the water tank, a tray motor 15, a water pump motor, a water inlet valve, a drain valve, The ultraviolet lamp 5 and the dryer 4 are connected with the control circuit. The core of the control circuit is a single-chip microcomputer.

An electric heater is arranged in the water tank, and the electric heater is connected with a control circuit through a temperature controller. The electric heater is used to heat the washing water to improve the washing effect, and its heating temperature is controlled by a thermostat. At the same time, an upper limit water level sensor and a lower limit water level sensor are arranged on the water tank wall, and the upper limit water level sensor and the lower limit water level sensor are connected with the control circuit to control the water intake of the water tank, so that the water level in the water tank is always between the lower limit water level and the upper limit water level.

This dishwasher uses high-pressure water cleaning as the basic principle. In the cleaning room surrounded by the inner shell, there are adjustable dish racks that can accommodate various tableware. The dish racks rotate smoothly and at a uniform speed driven by the tray. It is driven to rotate after the stage decelerates. The design of the dish rack should be easy to adjust, handle and clean, so it adopts a frame structure and is connected by stainless steel wires. The tray should not only support the dish rack, but also drive the dish rack to rotate, while not affecting the circulation of water. Because the bowl rack needs to rotate at a low speed and the total transmission ratio is large, the mechanical transmission part adopts two-stage reduction transmission, the first-stage transmission adopts V-belt transmission, and the second-stage reduction adopts micro cycloidal pinwheel reducer transmission. Several nozzles are evenly distributed on the inner wall. The water sprayed by the nozzles is pressurized by the water pump. The tableware on the dish rack is washed in all directions by the pressurized water column. The dish rack drives the tableware to rotate together to ensure that all parts of the tableware are cleaned.

Before washing dishes, first open the top cover to take out the dish rack, place the tableware to be washed on the dish rack, then place the dish rack on the tray through the positioning pins, cover the top cover and then clean. Because the tray rotates very low, the dish rack does not need to be fixed to the tray. First of all, the cleaning is carried out. The high-speed water flow from the nozzle scours the tableware, and the tableware rotates with the rack while washing, so that every part of the tableware can be cleaned, which not only improves the cleaning effect, but also saves water resources to a certain extent. After cleaning, the dryer installed under the cleaning chamber starts to work, and the hot air generated quickly dries the tableware. After drying, the ultraviolet lamp installed on the inner wall starts to work to sterilize the tableware. After that, the dishwashing process is terminated.

The temperature of the water, the time of cleaning, drying and disinfection, and the sequence of their execution will all be controlled by the single-chip microcomputer to ensure that the dishwashing process is carried out in an orderly manner as required. The general control mode of the single chip microcomputer is shown in Figure 4, and the whole circuit principle is shown in Figure 7.

The whole process of washing dishes in a dishwasher can be divided into five modules: start-up module, washing module, drying module, disinfection module, and end module. Selecting different modules corresponds to different working modes. This dishwasher has four working modes. There is a "mode" selection button on the dishwasher panel. The mode button provides four different modes. The system default is " standard wash".

Mode I is standard washing, including starting module, washing module, drying module, disinfection module and ending module;

Mode II is a quick wash, including a start module, a wash module and an end module;

Mode III is independent drying, including start module, drying module and end module;

Module IV is an independent disinfection, including a start module, a disinfection module and an end module.

There is a timer button on the dishwasher panel, set the time "timing" to control the time of washing dishes, according to the different, size and number of dishes, the time can be controlled by people, which is more humane, the default time given by the system is 10 Minutes, this time can be increased or decreased by button "+" and button "-", every time you press it, increase or decrease by 1 minute. The time range is from 5 minutes to 30 minutes.

In order to facilitate the operation of the machine, indicator lights and digital tube displays are set up on the panel. The indicator lights are divided into: indicator light 1 is the standard washing indicator light, which is always on during the standard washing process, and goes out after completion. Indicator light 2 is a quick washing indicator light, which is always on when performing quick dishwashing operations, and goes out after completion. The indicator light 3 is the drying indicator light, which is always on during the drying operation, and goes out after the drying operation is completed. Indicator light 4 is the disinfection indicator light, and when carrying out disinfection operation, this light is always on, and goes out after finishing. The warning indicator is the system error indicator, and it will be on when the system has an error. The digital tube mainly displays the set time, and the time is in minutes.
