Abstract
The utility model relates to an electric heating shower with a two-way power-off protective device, which comprises a controller which is composed of a relay; the controller is connected with a temperature controller and an electric heater respectively through a control switch. Because a closed type circuit is adopted, double wires of the whole circuit are completely controlled to be switched on or off through the relay, and a plurality of general indicating circuits can be added according to actual requirements, the utility model has the advantages of simple structure simple manufacture high safety, convenient operation and long service life.
Description
The utility model belongs to domestic water formula electric heating shower class, specifically is a kind of electric heating shower with the two-way power-off protection apparatus.
At present domestic electric heating shower adopted more is passed through temperature controller and the direct-connected structure of power supply, promptly control the break-make of power supply by temperature controller, even if the power supply indication is so in use arranged, also can't judge in good time correct power on/off situation in the machine, also just can't guarantee user's personal safety, so each just must be frequent when shower pull out, plug-in source plug, operate very inconvenient, and in a single day when shower, forget and pull out attaching plug, then be very easy to take place the major accident that the person gets an electric shock.
The purpose of this utility model be to provide a kind of simple in structure, be easy to make, safe and reliable, easy to use, the electric heating shower of the band two-way power-off protection apparatus that the life-span is long.
The utility model is achieved through the following technical solutions:
Be a kind of electric heating shower, comprise the controller of forming by relay, it is characterized in that controller links to each other with temperature controller and electric heater by gauge tap respectively with the two-way power-off protection apparatus.
The described controller of being made up of relay is to adopt multifinger relay, and in the power input contact of relay two are linked to each other with two power lines, two output normally opened contacts of its correspondence connect flirtatious heater by lead, one end of relay coil links to each other with power line, the other end connects gauge tap, and another contact of gauge tap links to each other with temperature controller simultaneously.
Be connected alarm between the normally-closed contact of described relay and the power line.
The utility model compared with prior art owing to adopted the closed type circuit, is controlled the complete break-make of entire circuit by relay, and can add some indicating circuits commonly used according to actual needs, so have the following advantages:
1, simple in structure, be easy to make.
2, safe and reliable, easy to use, the life-span is long.
Describe in further detail below in conjunction with accompanying drawing:
Fig. 1: the utility model embodiment circuit diagram.
Fig. 2: prior art embodiment circuit diagram.
As shown in Figure 1, the electric heating shower of this band two-way power-off protection apparatus comprises the controller of being made up of relay, and controller links to each other with temperature controller and electric heater by gauge tap respectively.
The described controller of being made up of relay is to adopt multifinger relay, and in the power input contact of relay two are linked to each other with two power lines, two output normally opened contacts of its correspondence connect electric heater by lead, one end of relay coil links to each other with power line, the other end connects gauge tap, and another contact of gauge tap links to each other with temperature controller simultaneously.
Be connected alarm between the normally-closed contact of described relay and the power line.
In use, regulate temperature controller KR as shown in Figure 1 to suitable temperature, connect power supply, then power supply indicator RD1, RD3 are bright, press manual knob AN, and relay J gets electric work, its normally opened contact JC1, the closed connection of JC2, JC3, normally-closed contact J1 disconnects, and indicator lamp RD3 to be heated extinguishes, the heating element heater W heating of switching on; When temperature reaches the predetermined value of temperature controller KR, temperature controller KR moves deenergization, this moment the relay J dead electricity, the normally opened contact JC1 of relay J, JC2, JC3 disconnects simultaneously, the complete dead electricity of heating element heater W, even if do not pull out attaching plug like this, the major accident that the person gets an electric shock can not appear yet, thereby reach the purpose of safety shower, that has eliminated that former shower exists reaches behind the predetermined temperature deficiency of deenergization fully, (former shower common circuit schematic diagram is seen Fig. 2,) after the relay J dead electricity, its normally-closed contact J1 recovers original closure state, when needs carry out alarm, also can connect an alarm Y by relay normally-closed contact J1, with after reaching predetermined temperature, the closed alarm Y that connects of the normally-closed contact J1 of relay J has reached design temperature by alarm Y alarm, the branch of this circuit reason relay J normally opened contact, leading to of incompatible control electric heater two-way while, outage is so guaranteed shower safety in use fully.
Claims (3)
