Description

Bathroom heater switch

Technical Field

The invention relates to the field of switches, in particular to a bathroom heater switch.

Background

The bathroom heater is an electrical appliance commonly used in our home life. Especially in recent years, the air heating bath warmer is not dazzling like light heating, does not have explosion danger like lamp heating, has more sufficient hot air, enables the bath and warming of the bathroom to be more convenient and safer, and is widely popular with consumers.

The air heating bathroom heater generally comprises a heating tube (wire), a blower and the like, wherein the heating tube (wire) generates heat after being electrified, and then the blower is required to blow hot air off to heat. In the process, after the heating tube (wire) heats, the blower must start to work, otherwise, the heating tube (wire) can always heat, the heat can not be dissipated, the heating tube (wire) can be burnt, and even a fire can be caused.

The existing solutions are two kinds: the utility model provides a be warm bathroom heater switch of interior electric wire circuit series connection wind, includes the shell, blows button, warm button etc. because the internal line of the button of blowing and warm button is established ties, also is exactly the live wire will be earlier through the button of blowing just can pass through warm button of wind, in the time of the use, opens the button of blowing earlier, then opens warm button of wind, gets warm. If the air-blowing key is not opened, the air-heating key is singly pressed, and the heating tube (wire) can not work. The design structure solves the problem of safe operation, but the key needs to be pressed for 2 times or more than 2 times for warming, so that the use of consumers is complicated; the other kind is with parallelly connected warm bathroom heater switch of air of internal circuit, erect a UNICOM's passageway in addition between warm button of air and the button circuit of blowing, like this, when opening warm button 42 of air, can open the circuit of blowing automatically, it is parallelly connected with the heating circuit also to blow the circuit, the operating problem of switch has been solved to this kind of structure, and is simple to use, and the heating can be opened to a button, this kind of structure, and the problem of existence is that switch internal circuit becomes complicated, and the appearance structure of switch is restricted. These two kinds of structures, a common problem still reaches the design purpose through the switch inner line, and the totality all makes the inner line more complicated, under the common trouble of circuit such as overload, short circuit, contact failure, the easy trip trouble of inner line will arouse heating tube (silk) dry combustion method like this, and uncontrollable, leads to the bathroom heater to burn out, takes place during this kind of condition.

In addition, two types of bath heaters are arranged on the market at present, one type of bath heater is a bath heater with double motors, and the two motors realize the functions of blowing and air exchange; the other bathroom heater only has one motor, namely one motor shared by blowing and ventilating, the motor is arranged above the heating tube (wire), the motor realizes two functions of blowing and ventilating through positive rotation and reverse rotation, the positive rotation blowing can blow heat of the heating tube (wire) down for people to warm, and the reverse rotation ventilating can exchange indoor air polluted by humidity and outdoor air. The single-motor bath heater only uses one motor, so the structure is simpler and more durable than that of a double-motor bath heater, and the cost is lower.

However, the single-motor bath heater also has some problems, and the switch corresponding to the single-motor bath heater is relatively complex in design and is more troublesome to use than the double-motor bath heater switch. Because the blower and the ventilation share one motor, the blower and the ventilation function cannot be arranged on two keys on a common switch, otherwise, the two keys are easy to press simultaneously, and the shared motor cannot work or even burn.

In order to solve the problem, the current solution is to arrange the air blowing and the air exchange on the same switch key, so that the air blowing or the air exchange is respectively carried out when the switch is pressed down, and the misoperation can never occur. The solution is to solve the problem that the single motor bath heater can not operate by mistake when the blower and the ventilation positive and negative rotation motor rotate, but a power switch key must be additionally arranged, otherwise, one of the blower and the ventilation always works. When the air blowing and ventilating switch is used, the power key must be pressed firstly, the motor key is electrified, one function is started firstly, then the motor key is pressed to switch air blowing and air exchanging from top to bottom, the use is complicated, and the consumer experience is not good.

Therefore, it is highly desirable to invent a bathroom heater switch that can not only realize one-key operation of air heating and blowing, but also prevent the simultaneous opening of blowing and ventilation.
