Abstract
The utility model discloses a control device of an electric hot water bottle, which comprises an RC (Resistor Capacitor) parallel circuit, a steam switch, a kicking type heat preservation switch, a bridge type rectifying circuit and a relay. The steam switch is communicated with a power supply after in parallel connection with the kick type heat preservation switch and is connected with the RC parallel circuit, and the other end of the RC parallel circuit is connected with the bridge type rectifying circuit which is in serial connection with the relay; the power supply is connected with one end of the relay with a contact, and the other end of the relay is connected with a parallel circuit of a heating plate and a heating red light; and one end of a heat preservation green light is connected with a power supply, and the other end of the heat preservation green light is connected between the contact of the relay and the parallel circuit of the heating plate and the heating red light. When in use, the heating red light is on, and when the temperature of the water in the bottle reaches 100DEG C, the steam switch is disconnected, the relay stops working, and the heat preservation green light is on; in a heating process, when the water temperature exceeds or is lower than heat preservation temperature, the kicking type heat preservation switch acts; and therefore, the purpose of heat preservation is achieved. Therefore, the utility model can ensure water is boiled and is not repetitively boiled after boiling.
Description
Technical field
The utility model relates to a kind of electric hot water bottle.
Background technology
Present prior art, a kind of control device of electric hot water bottle comprises temperature sensor, relay J, hand switch and electric capacity.Existing problems are: during use, as long as water in bottle reaches the water temperature of setting, just outage when being lower than the water temperature of setting, just adds hot water again, duplicates to add hot water, the waste electric energy.
Summary of the invention
The purpose of this utility model is: a kind of control device of electric hot water bottle is provided, and it can guarantee that the water in the bottle reaches boiling water, but also can be incubated, and prevents repeatedly to boil water.
The utility model is achieved in that a kind of control device of electric hot water bottle, and its special character is: it comprises RC parallel circuit, steam cock, Kick type insulation switch, bridge rectifier and relay;
Be communicated with power supply after steam cock and the Kick type insulation switch in parallel and be connected with the RC parallel circuit, the RC parallel circuit other end is connected with bridge rectifier, and bridge rectifier is connected with relay;
Contact one termination power of relay, the other end is connected with the circuit of heat-generating disc with the parallel connection of heating red light;
The contact that insulation green light one termination power, the other end are connected on relay is with heat-generating disc and heat between the red light circuit in parallel.
The control device of described a kind of electric hot water bottle, its special character is: also comprise a Kick type dry burning resistance switch, the Kick type dry burning resistance switch is connected between power supply and steam cock and the Kick type insulation switch in parallel circuit.
The control device of a kind of electric hot water bottle of the utility model, owing to adopt such structure, during use, the heating red light is bright, when the water in the bottle reached boiling water and requires to seethe with excitement, promptly water temperature reached 100 ℃, and steam cock disconnects, relay quits work, and the contact of relay disconnects, and the insulation green light is bright; In the process of heating, when temperature rose to above holding temperature, Kick type insulation switch disconnected; When temperature is reduced to when being lower than holding temperature, Kick type insulation switch closure, relay work, the heating red light is bright, reaches the purpose of insulation.So it can reach the assurance boiling water, and not to boil water repeatedly behind the boiling water.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of control device of electric hot water bottle is characterized in that: it comprises RC parallel circuit, steam cock K, Kick type insulation switch S 2, bridge rectifier and relay J;
Steam cock K is communicated with power supply and is connected with the RC parallel circuit with Kick type insulation switch S 2 backs in parallel, and the RC parallel circuit other end is connected with bridge rectifier, and bridge rectifier is connected with relay J;
Contact JK one termination power of relay J, the other end is connected with the circuit of heating red light L2 parallel connection with heat-generating disc R1;
The contact JK that insulation green light L1 one termination power, the other end are connected on relay J is with heat-generating disc R1 and heat between the red light L2 circuit in parallel.
After the energising, enter the insulation heated condition, press steam cock K, the contact JK closure of relay J, heat-generating disc R1 enters heated condition, and L2 is bright for the heating red light, and when temperature surpassed the holding temperature temperature range, insulation switch S 2 disconnected; Be heated to when producing steam, steam cock K disconnects, and relay J quits work, and heat-generating disc R1 stops heating, and heating red light L2 goes out, and enters keeping warm mode, and L1 is bright for the insulation green light.
When temperature drops to the holding temperature scope, insulation switch S 2 closures, relay J is started working, and enters the insulation heated condition, the heating red light is bright, and after temperature rose to the holding temperature scope, insulation switch S 2 disconnected, circuit enters keeping warm mode again, and the heating red light goes out, and the insulation green light is bright.
As further improvement of the utility model: also comprise a Kick type dry burning resistance switch S1, the Kick type dry burning resistance switch is connected between power supply and steam cock K and Kick type insulation switch S 2 parallel circuits.
Kick type dry burning resistance switch K3 is a normally closed switch, and when dry combustion method, Kick type dry burning resistance switch K3 disconnects, and prevents dry combustion method.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
