Combined switch for super bath

Abstract

A combination switch of a bath bully comprises a combination switch shell body and is characterized in that a wire led from a wire connecting terminal connected with a commercial power live wire is divided into three wires; one wire is connected with an output wire connecting terminal of a ventilator through a ventilation switch K1; the second wire is connected with an output wire connecting terminal of a second warming light and a second warming light switch K3 through a first warming light switch K2; the other end of the second warming light switch is connected with an output wire connecting terminal through a lighting switch K4; the third wire is connected with an output wire connecting terminal of the second warming light through the second warming light switch K3; the first warming light switch K2 adopts a selector switch; and the second warming light switch K3 adopts two option switches which are live optionally. No matter an illuminating lamp is on or off, as long as the first warming light or / and the second warming light is / are turned on and in a working state, the illuminating lamp can be automatically turned off. The combination switch can be more conveniently and naturally used, and the whole switch is designed more reasonably, thereby achieving the effect of saving energy and preventing the illuminating lamp from being on meaninglessly.

Description

technical field [0001] The invention relates to a bathroom heater combination switch. Background technique [0002] With the continuous advancement of technology and the continuous improvement of people's living standards, people widely use Yuba in the bathroom, and when installing Yuba, it is necessary to use a combination switch to control whether the heating bulb, ventilation fan and lighting work or not. The traditional Yuba combination switch has a combination switch shell, and four switches are respectively installed in the shell, which are the first light heating switch K2, the second light heating switch K3, the ventilation switch K1, and the lighting switch K4. In order to facilitate production and assembly, These four switches are wired in parallel to respectively control the four circuits of the first heating lamp, the second heating lamp, the ventilation fan and the lighting lamp. Although the circuit is simple, there is a defect in use, because each working circ...

Problems solved by technology

The traditional Yuba combination switch has a combination switch shell, and four switches are respectively installed in the shell, which are the first light heating switch K2, the second light heating switch K3, the ventilation switch K1, and the lighting switch K4. In order to facilitate production and assembly, These four switches are wired in parallel to respectively control the four circuits of the first heating lamp, the second heating lamp, the ventilation fan and the lighting lamp. Although the circuit is simple, there is a defect in use, because each working circuit is connected in parallel. , so, once the lighting lamp is turned on, when the first heating lamp or / and the second heating lamp are turned on and are in working condition, the lighting lamp is still on. In fact, the lighting lamp does not need to be lit at this time, resulting in waste of energy; in addition, Under normal circumstances, we are used to turn on the lighting first, do some preparations for taking a bath, and then turn on the heating lamp, but after the heating lamp is turned on, the lighting will not automatically turn off, and we need to press it again to turn it off, resulting in the use of Inconvenient, and, the first light warm switch K2, the second light warm switch K3, the ventilation switch K1, and the light switch K4 are the switch components of each unit connected by connecting wires, which causes inconvenience in manufacture and use, so , need to further improve the design
