The present invention relates to a method for controlling the rotation of a rotating device, and more particularly, to a method for controlling the reciprocating rotation of a rotating body within a section set in a rotating device having a rotating body such as a fan or a heating and cooling device.

In general, in a rotating device having a rotating body such as a fan or a fan of a heating and cooling device, the rotating body can be selected by a user to fix or reciprocate a predetermined section. In this case, when the fixed mode is selected, the wind direction is selected only in one direction desired by the user. When the reciprocating mode is selected, the wind direction is reciprocated within a predetermined section. Typically, the reciprocating section is fixed by the manufacturer uniformly during manufacturing, so that the user can not change. Accordingly, there is a problem that not only unnecessary power is wasted but also the response is slowed because the rotation is made to an unnecessary section.

Accordingly, an object of the present invention is to provide a rotation control method in which a user can arbitrarily select a reciprocating rotation section of a rotating body.

Another object of the present invention is to provide a rotation control method in which a user can easily select a reciprocating rotation section by using only a single function key provided in the existing rotating device.

The present invention for achieving the above object is characterized by setting the reciprocating rotation section of the rotating body in response to the user's selection, and rotating the rotating body within the reciprocating rotating section.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description, it should be noted that like elements in the drawings represent the same reference numerals wherever possible. In addition, in the following description, numerous specific details such as specific flow charts, keystrokes, flags, etc. are shown to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 shows a block diagram of a rotating apparatus according to the present invention. The position detection sensor 100 detects the position of the fan of the rotating chain and generates a signal according to the position. As the position detection sensor 100, a volume resistor may be used. The key input unit 102 is provided with a conventional rotary key for setting the reciprocating rotation mode. The microcomputer 104 converts and inputs the signal of the position detection sensor 100 through A / D conversion input terminal A / D and inputs the fan driver according to the key input from the key input unit 102. The controller 106 controls the speaker driver 108 and the rotation direction controller 110. The fan driver 106 drives or stops the fan under the control of the microcomputer 104. The speaker driver 108 generates a sound informing the operation state by driving the speaker under the control of the microcomputer 104. The rotation direction controller 110 selects the rotation direction of the fan, that is, the forward rotation or the reverse rotation, under the control of the microcomputer 104.

2 is a flow chart illustrating a rotation control according to the present invention, which shows a process of setting one of a reciprocating rotation mode and a fixed mode in response to a rotation key input and setting a reciprocating rotation section.

Hereinafter, with reference to Figures 1 and 2 attached to the operation example of the present invention will be described in detail.

First, the microcomputer 104 checks whether the rotation key is input from the key input unit 102 in step 200 of FIG.

At this time, if there is a rotation key input, the state of the rotation flag is checked in step (202). The rotation flag is a flag for distinguishing the rotation start state from the rotation end state, and uses a buffer provided in the microcomputer 104. For example, in the reset state, the rotation start state is indicated, and in the set state, the rotation end is completed. Status, and the initial status is reset status.

If the rotating flag is started in step 202, the value output from the position detection sensor 100 at that time is stored as a starting point value of the reciprocating rotation section in step 204, and the fan driving unit 108 in step 206 is performed. ) To drive the fan and control the rotation direction control unit 110 to start the reciprocating rotation. The reciprocating section means a section for reciprocating the fan. In step 208, the rotation flag is set to the end and the section flag is reset to the start. The section flag is a flag for distinguishing the start state and the rotation state of the section, and uses a buffer provided in the microcomputer 104. For example, the section flag indicates the start of the section and the end of the section in the set state. Indicates. After that, the timer is driven in step 210, and the speaker driver 108 is controlled in step 212, and the start sound is generated. The timer is set to a time value for checking the number of rotation key inputs within the set time.

If the rotation flag is finished in step 202, the value output from the position detection sensor 100 is stored as an end point value in step 214. In step 216, the rotation flag is set to start and the section flag is set. To the end. Thereafter, in step 218, the speaker driver 108 is controlled to generate an end sound and then terminate.

In addition, if there is no rotation key input in step (200), and checks the state of the section flag in (220), (226). At this time, if the section flag starts, check if the timer has timed out in step 222 and terminates if it has not timed out, and if it has timed out, reset the rotating flag to start in step 224 and then end it. do. In contrast, when the section flag is set to the end, the difference between the start point value and the end point value, that is, the reciprocating rotation section value, is compared with the preset reference value K in step 228. In this case, if the reference value K is smaller than the reference value K, the rotation direction controller 110 is set to the fixed mode to fix the rotating body. If the reference value K is greater than the reference value K, the rotation direction control unit 110 is set to the reciprocating rotation mode in step 232. The fan is reciprocated in the reciprocating section.

The above is summarized as follows. If the rotation key is input twice during the set time of the timer, the fan position at the first input is determined as the starting point of the reciprocating section, and the fan position at the second input is determined as the end point of the reciprocating section. The reciprocating section value between the start point and the end point is compared with the reference value K and set to the fixed mode if it is smaller than the reference value K, and set to the reciprocating mode if it is larger than the reference value K. When the rotation key is input once within the set time, the fan is reciprocated within the previously set reciprocation section. If the rotary key is not input within the set time, the previous operation state is maintained.

As described above, the present invention has an advantage that a user can arbitrarily select a reciprocating rotation section simply by using only a single function key provided in the existing rotating device.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Particularly, in the embodiment of the present invention, the fixed mode or the reciprocating rotation mode is set along with the rotation key input, and the reciprocating rotation section is also set. However, the mode setting and the reciprocating rotation section may be separated. In addition, it is equally applicable to all devices reciprocating a certain section as well as rotation. Therefore, the scope of the invention should not be defined by the described embodiments, but should be defined by the equivalents of the claims and the claims.
