Problems solved by technology

1: The human body is more likely to suffer from discomfort and damage when exposed to hot air for a long time; 2: Once the fan heater stops working at night, the indoor temperature will drop rapidly, seriously affecting the quality of sleep or endangering the health of the body, especially for the elderly and children; 3: Warming The fan consumes a lot of power, generally more than 1000W. Turning on the fan all night will greatly increase the cost of use for consumers and reduce the service life

Embodiment Construction

[0019] Such as figure 1 Shown is the functional block diagram of the cycle timing electric fan of the present invention, as can be seen from the figure, this fan has increased the cycle timing function on the basis of the ordinary fan, including connecting the running time setting unit 2 with CPU1 with timing function respectively , stop time setting unit 3, cycle number setting unit 4 and storage unit 9. The control instructions input by the running time setting unit 2, the stop time setting unit 3, the cycle number setting unit 4, the wind speed setting unit 7 and the wind type setting unit 8 are all stored in the storage unit 9 after being processed by the CPU1 , CPU1 reads the control command from the storage unit 9 and outputs it to the motor circuit 5 to drive the motor 6, so that the fan can work according to the user's setting.

[0020] In the embodiment of the present invention, adopt the microprocessing chip of Taiwan Holtek Semiconductor Company, its model is HT48R...

Abstract

A fan with cyclic timing function is composed of fan blades, drive motor and control circuit, and features that said control circuit consists of CPU with timing function, running time set-up unit, stop time set-up unit, number-of-cycles set-up unit and memory unit. It can automatically perform the cyclic operation of turn-on and turn-off.

Description

technical field [0001] The present invention relates to a fan, and more specifically relates to a fan with the function of cycle timing start and stop. Background technique [0002] In the hot summer, electric fans are especially widely used because of their much lower cost and power consumption than air conditioners. But continuous use of electric fans for a long time will make people obviously feel uncomfortable, and even cause great harm to the human body, especially for the elderly and children, even the simulated natural wind or sleeping wind should not be used for a long time. Therefore, the existing electric fans and air-conditioning fans generally have the function of timing shutdown. The method is to pre-set the length of time required to run through an electronic or mechanical timer. When the running time reaches the set time length, it will stop running immediately. . [0003] The timer stop function brings convenience to people when using the electric fan, and ...
