Embodiment
In order to allow those skilled in the art more understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, indoor heater control circuit of the present utility model is further described.
A kind of indoor heater control circuit, normally, efficiently works for control and protection indoor heater.This circuit can be divided into two parts, and a part is heating circuit, and another part is blowing circuit, as shown in Figure 2.
Concrete, heating circuit is made up of power switch K1, heating load R1 and protection switch S1, and power switch K1 one end access live wire, the other end is connected with the input end IN of heating load R1.Generate heat load R1 output terminal OUT then with being connected of protection switch S1, last protection switch S1 is connected on zero line, and make heating circuit form a complete loop when power switch K1 closes, heating load R1 starts heating.In preferred embodiment, protection switch S1 adopts normally closed type temperature detect switch (TDS) usually, when household heater work break down cause heating load R1 excessive heating time; heating temp exceedes safe temperature; protection switch S1 then disconnects automatically, cuts off heating circuit, and heating load R1 stops heating.Use due on market the temperature detect switch (TDS) that automatically resets, although can realize excess temperature power-off protection, when temperature is reduced to the reset temperature of protection switch S1, protection switch S1 will automatically reset closed, circuit turn-on, and electrical equipment is resumed work more.And the fault of product reality and potential safety hazard are not got rid of thoroughly, user layman, not clear to the judgement of fault, product tape fault continuous firing, will produce huge potential safety hazard, just in case temperature controller break function lost efficacy, temperature controller will keep conducting state, there is long-time continuous heat temperature raising state in product, internal part is heated, and causes fire or security incident.Therefore, in the present embodiment, protection switch S1 preferably adopts the hand reset temperature detect switch (TDS) of normally closed type, and the critical temperature of setting can carry out change adjustment according to product, can be set to 80 DEG C under preferable case.Must be resetted by staff after protection switch S1 disconnects, otherwise cannot to be worked on, with protection circuit better, avoided security incident.
In blowing circuit, blowing circuit outwards transmits as early as possible for assisting the heat by heating circuit produces, comprise the blower fan M1 of time relay RL1 and the diffusion of auxiliary heating load R1 heat energy, described time relay RL1 comprises the zero line side N connecting zero-power line, the live wire end L connecting described power switch K1 and the intermediate node of described heating load R1, is connected the input end IN of power firestreak and connects the output terminal OUT of described blower fan M1, and described blower fan M1 also connects described zero line and ground wire formation performance loop.Generally, the time relay RL1 in the present embodiment is divided into normal power supply, time delay is powered and power-off three kinds of duties.Wherein, zero line side N and live wire end L provides status signal for relay, when zero line side N and live wire end L connect and beam conduction time, time relay RL1 will be in normal power supply state.Now, connect the input end IN of power firestreak and the equal conducting of output terminal OUT of connecting fan M1, blower fan M1 runs well, and is outwards blown out by the heat that heating load R1 produces.When power switch K1 disconnects, live wire end L and the connection between heating load R1 and power firestreak disconnect, heating load R1 stops heating, time relay RL1 then enters time delay power supply state, output terminal OUT continues as blower fan M1 and powers, blower fan M1 continues blowing, is taken away as early as possible by the waste heat of heating load R1.After time delay reaches setting-up time, output terminal OUT is corresponding disconnection also, and time relay RL1 enters off-position, then blower fan M1 quits work.In preferred embodiment, time relay RL1 is provided with the time delay knob of adjustable delay length.Delay duration adjusts according to the heating power of heating load R1 and the needs of user, is preferably 1 minute or more.
In addition, in other embodiments, as shown in Figure 3, in order to operate well heater better, on the basis of a upper embodiment, time relay RL1 also comprises connection first reset terminal RESET1 and the second reset terminal RESET2, and described first reset terminal RESET1 is connected by a button switch K 2 open in usual with the second reset RESET2 end.In random time after time relay RL1 enters time delay power supply state, press button switch K 2 open in usual, time relay RL1 will be reset, and enter off-position.In the present embodiment, the model of time relay RL1 is ST3PF.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
