Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ceiling fan with a speed regulating device.

BACKGROUND OF THE INVENTION Conventionally, this type of ceiling fan has had a configuration as shown in FIG. That is, the motor section 100 is composed of a series circuit 103 consisting of an auxiliary winding 101 and a capacitor 102, and a main winding 104 connected in parallel to these. , and a speed changeover switch 203 for switching these, and the speed adjustment device 2oo was inserted into a current supply circuit from a power source 300 to the electric motor section 10o.

In this circuit, speed adjustment is performed by a speed changeover switch 203.
By operating , the electric motor section 100 and the power supply 300 are directly connected, and the capacitor 201 is inserted.

Select whether to insert the capacitor 202 and set it to strong, medium, or
It was configured to switch to weak.

Problems to be Solved by the Invention With such a conventional configuration, once a ceiling fan is operating at a set notch, there are cases where the room temperature gradually rises and a strong wind speed is desired, and when the room temperature is low and a strong wind speed is not required. Even if the speed changeover switch is not operated, the speed changeover switch is operated at the same speed unless the speed changeover switch is operated intentionally, so there is a problem that the wind speed cannot be adjusted immediately according to the room temperature.

The present invention solves the above-mentioned conventional problems, and aims to provide a ceiling fan that can automatically adjust its speed so as to obtain a wind speed corresponding to the height of the room temperature.

Means for Solving the Problem In order to solve this problem, the present invention provides an electric motor, a changeover switch connected in series with the electric motor, and a changeover switch selected by the changeover switch and connected in series with the electric motor. It is composed of a plurality of speed adjustment sections, a control device for controlling the changeover switch, and a temperature sensing device that senses the room temperature and sends a signal to the control device.

Operation With this configuration, the temperature sensing device senses the room temperature and sends a signal to the control device, and the control device operates the changeover switches of the plurality of speed adjustment devices, so that the speed adjustment section is automatically selected. The motor rotation speed is adjusted to obtain a wind speed that corresponds to the room temperature.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, reference numeral 1 denotes a motor section, which is composed of a series circuit consisting of an auxiliary winding 4 and a capacitor 5, and a main winding 7 connected in parallel to these. The speed adjustment device 2 is composed of a notch changeover switch 14, a high temperature adjustment section 10 equipped with a plurality of capacitors 8 and 9, and a low temperature adjustment section 13 equipped with a plurality of capacitors 11 and 12. 3 is inserted into the current supply circuit to the motor section 1. By operating the notch changeover switch 14, the speed control device 2 can switch between high, medium, and low by directly connecting the motor section 1 and the power source 3 and inserting a capacitor 8 or a capacitor 9 at high room temperatures. In addition, when the room temperature is low, connect the motor section 1 and power supply 3 directly, insert capacitor 12 or capacitor 11, and set high, medium,
The configuration is such that the weak mode can be switched and selected. The electric motor section 1
A changeover switch 17 is provided between the speed adjustment device 2 and the speed adjustment device 2. This changeover switch 17 switches between the high room temperature adjustment section 1o and the low room temperature adjustment section 13 of the speed adjustment device 2, and connects the speed adjustment device 2 and the motor section 1 in series. It is connected to a temperature sensing device 16 which senses the room temperature and sends a signal to the control device 16 via a control device 16 which controls the switching of the temperature sensor 17 .

The operation of the ceiling fan of this embodiment configured as described above will be explained below. First, when the room temperature is high and a strong wind speed is desired, the temperature sensing device 15 senses the room temperature and sends a signal to the control device 16, and the control device 16 controls the changeover switch 17 to switch the high temperature adjustment section 1o to the electric motor. Since it is connected in series with section 1, the rotational speed of the medium/low notch is set high, resulting in speed adjustment as shown in speed adjustment characteristic 18 in the graph of FIG. Further, when the room temperature is low and a weak wind speed is desired, the temperature sensing device 15 senses the room temperature and sends a signal to the control device 16, and the control device 16 controls the changeover switch 17 to change the low room temperature adjustment section 13 to the electric motor section 1. Since the rotation speed of the medium/low notch is set low, the speed adjustment becomes as shown in speed adjustment characteristic 19 in the graph of FIG. 2.

As described above, according to this embodiment, the temperature sensing device 16 senses the room temperature and automatically adjusts the rotation speed according to the room temperature, so when the room temperature is high, the rotation speed of the medium/low notch is If the room temperature is low, the rotation speed of the medium/low notch will be set low, so you can obtain a comfortable wind speed according to the room temperature.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the temperature sensing device detects the room temperature and sends a signal to the control device. Since the changeover switch that changes the speed adjustment section of the ceiling fan can be changed, the adjustment range of each notch of the speed adjustment device is automatically changed to the rotation speed according to the room temperature, resulting in the effect that the ceiling fan can be used comfortably throughout the year. .
