Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a two-way pull string of an electric appliance.In addition to soldering to a one-stage or multi-stage mechanical switch, the pull string is set on an optical sensor, and the pull string is mechanical or electronic. Or use them alternately.

[0002]

[Prior art]

 Known hanging pullstring switches have been used by people for decades. Suspended drawstrings are used for electrical appliances, especially at high places, such as hanging fans and electric lights. The length of the pull string can be conveniently adjusted by adjusting the height of the electrical equipment installation. The other hanging straps are in the air, so there is no need to install additional straps and they do not take up space.

[0003]

[Problems to be solved by the invention]

 However, this type of pull string has the following problems. First, as shown in FIGS. 1 to 4, extend the hand forward, touch the pull string 1, open the hand, grasp the pull string 1, and pull the pull string 1 in the hand downward. Then, the user must loosen his hand and release the pull string 1. These operations seem to be simple, but in practice they are complicated and inconvenient, and they must be performed reliably. If you try to grab the pull string 1 without certainty, you cannot move on to the next operation. In addition, when the pull string 1 is pulled down to switch the switch, the pull string 1 is not vertical and when the power is pulled, the switch cannot be normally switched or operated. Therefore, when the operation is performed using the known pull string 1, the directionality is limited, and it is troublesome. At the same time, the force of the pull string 1 must be appropriate. If the force is too strong, the switch will be broken; if it is too small, the switching operation will not be performed. In addition, if the pull string 1 is not firmly caught and slipped, the pull string 1 may move on its own, and if the user attempts to grab the pull string 1 again, the user may encounter a difficult situation. At this time, the hand and the pull string 1 come into contact with each other many times, and the swing of the pull string becomes small, and then the grip can be finally grasped. For this reason, we propose a two-way pull string for electric appliances that solves the above problems.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the dual-purpose pull cord of the present invention is used as a pull string for opening / closing or multi-stage control of the electrical product when the dual-purpose pull string of the electrical appliance is installed on the electrical product to be controlled. It can be installed on single-stage or multi-stage mechanical switches, and also on optoelectronic sensors. The operation is controlled not only by a mechanical switch but also by an optoelectronic sensor based on contact or approach. For this reason, both mechanical switches and electronic sensors can be attached to electrical appliances, so that they can be used if they are familiar with either operation. That is, according to the present invention of claim 1, the two-purpose pull cord of the electric appliance is mainly installed on the electric appliance, and the pull cord hanging down on the electric appliance is installed on the mechanical switch or the opto-electronic type. It is installed on the sensor or the optoelectronic sensor on the pull string, and the control signals generated by both the mechanical switch and the optoelectronic sensor are interacted with each other, The control signals of different control methods both have the ability to control electric appliances, reduce the control mistakes of electric appliances, and get used to either operation. This is a two-purpose pull string for electric appliances, which is also applicable to those who have it. According to a second aspect of the present invention, the optoelectronic sensor is of an electrostatic type, a capacitor type, an electric resistance type, a current type, a voltage type, a vibration type, a temperature type, a magnetic field type, or the like. It is a two-way pull string of the electric appliance of claim 1. Furthermore, the present invention of claim 3 is the dual-use pull string of the electric appliance according to claim 1, wherein the pull string is rod-shaped.

[0005]

[Embodiment of the invention]

 Hereinafter, an embodiment of a two-way pull cord of the present invention will be described with reference to the drawings. First, as shown in FIG. 5, the present invention includes a mechanical switch 3, an opto-electronic sensor 4, and a pull string 2, wherein the pull string 2 is a flexible string and one of the pull strings 2. At the end, a mechanical switch 3 is installed, and when the operator pulls the pull string 2 downward, a switching operation of the mechanical switch occurs to control the electric appliance. At the same time, if the pull string 2 is placed on the photoelectric sensor 4 or the optoelectronic sensor 4 is placed on the pull string 2, only touching or approaching the pull string 2, A signal is sent and controlled. Therefore, the control effect and operation are performed by the contact, clapping and non-contact methods, and furthermore, there is no restriction on the direction of operation and there is no appropriate restriction of the force, and the operation of the appliance can be performed in a different way, which is convenient.

[0006] At the same time, when the mechanical switch 3 and the optoelectronic sensor 4 on which the above-described pull cord 2 is installed are pulled or touched, a control signal is sent to the control device, and the control device opens and closes the electric appliance. Adjustments are made. Therefore, when opening / closing or adjusting the electric appliance by the method of pulling the pull string 2 or the method of contacting or approaching, the control signals of both operate alternately. For example, the first time, the mechanical switch 3 is pulled to turn on the electrical appliance, and the second time, the mechanical switch 3 or the opto-electronic sensor 4 is pulled to open, close, or adjust the electrical appliance according to the control signal generated when touching or approaching. Do. For this reason, the pull string 2 has a dual-use effect. Even if the mechanical switch 3 or the opto-electronic sensor 4 breaks, the unbreakable opto-electronic sensor 4 operates and the mechanical switch 3 works, thereby reducing mistakes in electrical control. Also, since both are combined, if you are accustomed to either operation, you can use it and the range of users will be expanded.

Further, as an effect of the pull string 2 on the electric appliance, different controls and adjustments are performed by touching or approaching the pull string 2 several times. For example, when the pull string 2 of the present invention is installed on a hanging fan, when it responds to the first contact and approach, the wind speed of the fan is controlled, and the second contact and approach to the pull string 2 again. Doing so switches the wind speed one step further. As described above, the operation becomes convenient due to the multi-stage control effect.

[0008]

[Effect of the invention]

 As described above, the dual-purpose pull cord of the present invention can be used to control the opening / closing of electric appliances or a multi-stage control when installed on the electric appliance to be controlled. It can be installed on single-stage or multi-stage mechanical switches and also on optoelectronic sensors. The operation is controlled not only by a pulling mechanical switch but also by an optoelectronic sensor based on contact or approach. For this reason, it has the feature that it can be installed on electrical products with either mechanical switches or electronic sensors. Thereby, the pull string is effective to use mechanically, electronically or alternately.
