Abstract
The utility model discloses a circuit board for household electrical appliance; and the circuit board is provided with an on-line program burning interface and a CPU processing chip with repeat erasing function. The circuit board is provided with the on-line program burning interface and the CPU processing chip with repeat erasing function; when CPU program needs to update, the CPU program can be directly burned on-line, so research and development cost is greatly saved; and the circuit board is timesaving and laborsaving.
Description
Technical field
The utility model relates to a kind of circuit board for household electrical appliances.
Background technology
At present, many household electrical appliances adopt the circuit control panel with software programming.In product development stage, always have inconsiderate full place, therefore often change software, the situation of burning CPU program again needing to appear.For this kind situation, the way of usually taking is that the monoblock circuit board is replaced, or the CPU process chip is welded, and then changes the CPU process chip.If the monoblock circuit board is replaced, then can cause very large waste; And the method for CPU process chip is fallen in welding since the CPU pin often, closeer, therefore not only be difficult to welding and fall, waste time and energy, and weld easily bad printed board, still can cause very large waste.
The utility model content
Technical problem to be solved in the utility model provides a kind of circuit board that is used for household electrical appliances that can direct-on-line burning CPU program.
In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of circuit board for household electrical appliances is provided with an online burning program interface, and can repeats erasable CPU process chip on the described circuit board; The output of described online burning program interface is connected with the input of CPU process chip.
After having adopted technique scheme, the utlity model has following beneficial effect: the utility model is by being arranged on sequence of threads burning interface at circuit board, and adopt and to repeat erasable CPU process chip, when the CPU program need to be upgraded, can direct-on-line burning CPU program, greatly saved R﹠D costs, time saving and energy saving.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structured flowchart of the present utility model.
Label in the accompanying drawing is:
Circuit board 1, online burning program interface 2, CPU process chip 3.
Embodiment
(embodiment 1)
See Fig. 1, being used for of present embodiment is provided with an online burning program interface 2 on the circuit board 1 of household electrical appliances, and can repeat erasable CPU process chip 3; The output of described online burning program interface 2 is connected with the input of CPU process chip 3.
The circuit board 1 that is used for household electrical appliances of present embodiment, when needs are upgraded to the CPU program, can be by online burning program interface 2 direct-on-line burning CPU programs, neither need to change circuit board, do not need again to change CPU process chip 3, greatly saved R﹠D costs, time saving and energy saving.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
