Abstract
A novel microwave oven with a digital screen relates to the application of LED modules, and comprises a chip, a PCB (Printed Circuit Board) and a plastic sleeve. The chip is fixedly connected on the PCB, the plastic sleeve is sheathed outside the chip, and epoxy resin is filled between the plastic sleeve and the PCB for encapsulation. The chip consists of 78 8mil LED green illumination chips which are divided into six groups, and the 13 LED chips in each group are parallelly connected. The novel microwave oven with the digital screen has the benefits that the novel microwave is integrated via adopting a plurality of LED chips, the installation is convenient, and the assembly cost and the material cost are reduced; the product reliability is enhanced via adopting one-step encapsulation; owing to epoxy resin encapsulation, large-area heat radiation is achieved, the service life of digital tube chips is prolonged, the display to the function is highly concentrated, and the data wires and the signal wires are saved; and the production cost of downstream enterprises is saved, the appearance is attractive, and the display is clear.
Description
Technical field
The utility model relates to the application of led module, specifically is a kind of novel novel microwave oven digital screen.
Background technology
Micro-wave oven is a kind of modernization cooking kitchen range with microwave heating of food, by power supply, magnetron, control circuit and cooking cavity etc. are partly formed, power supply provides about 4000 volts of high pressure to magnetron, magnetron is under the power supply excitation, produce microwave continuously, pass through Wave guide system again, be coupled in the cooking cavity, near the inflow point of cooking cavity, a rotatable stirrer is arranged, because stirrer is the metal of fan shape, the reflection that after rotation is got up microwave is had all directions, so can be evenly distributed in microwave energy in the cooking cavity, thereby heat food.And control each grade culinary art by control panel, microwave oven control panel on the existing market is provided with a plurality of charactrons and shows to satisfy demonstration time, temperature and other menu, traditional has mechanical timer to show and most sign indicating number demonstration, because many charactrons show, displaying contents is single, can't complete microwave oven power, and in the single channel design, need to reserve a plurality of data-signals input port, need great amount of manpower in the equipment process.
The utility model content
It is a kind of by the led module application that technical problem to be solved in the utility model is to provide, and reduces a plurality of digital application failure rates, reduces the novel microwave oven digital screen of enterprise cost.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of novel microwave oven digital screen, constitute by chip, pcb board, plastics external member three parts, chip is fixed on the pcb board, plastics external member on the outer cover, the filling liquid epoxide resin material encapsulates between plastics external member and pcb board, it is characterized in that: described chip is made up of 78 8mil LED green glow chips, described 78 chips is divided into 6 groups, the parallel connection of every group 13 LEDs chip.
Draw 20 data control signal mouths on the described pcb board, a part is as public positive voltage control pin, and another part is controlled pin as negative pole.
After filling encapsulation by liquid epoxy material between described plastics external member and the pcb board, be 80 ° also by temperature, 10 hours baking moldings.
The beneficial effects of the utility model are multi-chip integrated LED micro-wave oven digital screens, be convenient to install minimizing assembly cost and material cost, disposable encapsulated moulding, increase reliability of products, adopt epoxy encapsulation, can large tracts of land dispel the heat, prolong the serviceable life of charactron chip, function shows high concentration, reduces the use of data line, signal wire.Save the production cost of down-stream enterprise, appearance looks elegant is generous, shows clear.
