Further, this transmission control device and this receiving control device adopt wireless transmission method to communicate to connect.Preferably employing bluetooth module carries out radio communication connection.
Storage-type electric water heater of the present invention can allow user be disconnected completely by water heater power supply before touching water, thus guarantees to be perfectly safe.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the storage-type electric water heater of embodiments of the invention 1;
Fig. 2 is the schematic diagram of the storage-type electric water heater of embodiments of the invention 2.
Detailed description of the invention
For further illustrating each embodiment, the invention provides drawings attached.These accompanying drawings are a part for disclosure of the present invention, and it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated to explain the operation principles of embodiment.Coordinate with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantage of the present invention.Assembly in figure not drawn on scale, and similar element numbers is commonly used to assembly like representation class.
Now the present invention is further described with detailed description of the invention by reference to the accompanying drawings.
Embodiment 1:
Consult shown in Fig. 1, as the storage-type electric water heater of one embodiment of the present of invention, the outlet pipeline of this storage-type electric water heater is installed one for detecting the water pressure sensing device 10 of hydraulic pressure, this water pressure sensing device 10 connects a transmission control device 20, the current supply circuit of this storage-type electric water heater is connected in series a switching device 30, and this switching device 30 connects a receiving control device 40.Other parts of the storage-type electric water heater of this embodiment are identical with the conventional storage-type electric water heater of prior art, also comprise water heater host, have cold water pipeline, hot water line, UNICOM's cold water pipeline and hot water line mixed water valve, tap, relief valve etc., no longer describe in detail in this.Wherein, this water pressure sensing device 10 is arranged on the export pipeline of mixed water valve of this storage-type electric water heater.
The hydraulic signal of detection is transferred to this transmission control device 20 by this water pressure sensing device 10, and this transmission control device 20 knows the water route break-make situation of water heater according to this hydraulic signal; When user uses water heater, the hydraulic pressure of the outlet pipeline of water heater produces, and when user closes water heater, the hydraulic pressure of the outlet pipeline of water heater loses.Water route break-make is judged that signal is sent to this receiving control device 40 by this transmission control device 20, and the current supply circuit that this receiving control device 40 judges signal according to this water route break-make received and then controls this switching device 30 pairs of storage-type electric water heaters carries out turn-on and turn-off operation.
The control mode of this receiving control device 40 is: judge that signal represents that water route is opened when receiving water route break-make, then controlling this switching device 30 makes the current supply circuit of storage-type electric water heater turn off, judge that signal represents that water route turns off when receiving water route break-make, then control this switching device 30 and the current supply circuit of storage-type electric water heater is opened.
The power supply of existing water heater may be all conducting (whether break-make controls primarily of the water temperature of temperature controller according to tank) in using state or non-working condition.But the water heater of this embodiment is different with it, when user's active deenergization when using water heater, in whole use procedure, the current supply circuit of water heater is disconnect, until just conducting again of finishing using always.Therefore, in use, water heater power supply is disconnected must produce any electrical hazard, thus guarantees to be perfectly safe.
Same as the prior art, this storage-type electric water heater is also arranged an independent current source switch 50, carry out turn-on and turn-off operation for the manual current supply circuit to storage-type electric water heater.
In this embodiment, transmission control device 20 and this receiving control device 40 adopt transmission cable to be connected, and the two can adopt the mode of universal serial bus to communicate.
Embodiment 2:
Consult shown in Fig. 2, the storage-type electric water heater of this embodiment is substantially the same manner as Example 1, difference is: transmission control device 20 and this receiving control device 40 of this embodiment adopt wireless transmission method to communicate to connect, thus avoid the loaded down with trivial details of wiring.Preferably employing bluetooth module carries out radio communication connection.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing from the spirit and scope of the present invention that appended claims limits; can make a variety of changes the present invention in the form and details, be protection scope of the present invention.
