Abstract
The utility model discloses an AC/DC double-purpose solar energy water heater controller, comprising a water temperature water level detection control circuit, a controller shell, a display screen, a function setting key, a dry battery cabin and an AC power line, wherein the AC power line is connected with an AC/DC adapter and commonly connected with a work circuit of the controller together with a DC power supply and an automatic switch device K is arranged between the DC power supply and the work circuit of the controller; the automatic switch device K is at the open position when AC power supply is used and the automatic switch device k is at the close position when the power is turned off or AC power supply is turned off; the controller uses the dry battery to supply the power. The work power supply can be the DC power supply or AC power supply and the power supply line of the AC power supply can be insert-draw type.
Description
Technical field
The utility model relates to a kind of controller, relates in particular to a kind of solar water heater controller of AC/DC.
Background technology
Solar water heater controller is extensively applied to solar energy heat utilization field as the instrument of demonstration and control solar water heater water-temperature water-level, and its function and control method also are gradually improved.Traditional solar water heater controller generally adopts Alternating Current Power Supply, perhaps adopts dry cell direct current supply, and the former is in outage or can't operate as normal when not having power supply, and the latter then needs often to change dry cell, and the use of controller is brought inconvenience.
Summary of the invention
The utility model is intended to invent a kind of solar water heater controller that can adopt the power supply of AC and DC power supply simultaneously.
For achieving the above object, the technical solution of the utility model is: a kind of solar water heater controller of DC-AC two-use, comprise that water-temperature water-level detects control circuit, controller housing 1, display screen 2, function setting key 3, aforesaid solar water heater controller also comprises dry cell storehouse 4 and AC power cord 5, AC power connects the operating circuit that AC-DC adapter and dc source are connected controller jointly, between dc source and controller operating circuit, be connected with auto switching device K, auto switching device K is in open position when Alternating Current Power Supply, when outage or AC power disconnection, and auto switching device K closure.Controller AC power cord 5 is a plug type.
Adopt the solar water heater controller of above-mentioned design can utilize Alternating Current Power Supply or dry cell direct current supply.When exchanging input, AC power provides power supply by the AC-DC adapter for the operate as normal of controller, when not exchanging input when not having power supply (as outage or), can provide power supply for controller work by dc source (dry cell).
Above-mentioned solar water heater controller can guarantee that controller can not influence operate as normal because outage waits other reasons, satisfies the water needs in any moment of user.Simultaneously, for conveniently checking water-temperature water-level, the general user is installed in controller between bathing, and the socket of installing between general bathing is few, because AC power cord 5 is a plug type, when needs use socket, the AC power cord plug is taken down, can be vacateed socket.
Description of drawings
As Fig. 1 is the internal work line frame graph of solar water heater controller of the present utility model.
As Fig. 2 is front schematic view of the present utility model.
As Fig. 3 is schematic rear view of the present utility model.
The specific embodiment
Internal work line frame graph of the present utility model as shown in Figure 1, AC power connect the operating circuit that AC-DC adapter and dc source are connected controller jointly, for the normal operation of controller provides the energy.Be connected with auto switching device K between dc source and controller operating circuit, auto switching device K is in open position when Alternating Current Power Supply, when outage or AC power disconnection, and auto switching device K closure, controller utilizes dry cell power supply.
Controller of the present utility model comprises controller housing 1 shown in Fig. 2,3, display screen 2, function setting key 3, aforesaid solar water heater controller also comprises dry cell storehouse 4 and AC power cord 5, working power both can be a dc source, also can be AC power, and the power line 5 of AC power be a plug type.
Above-mentioned solar water heater controller can satisfy the needs that any moment of user uses hot water, and is easy to use and reliable, solved the difficulty of water and heating on can not normally carrying out when outage, also solved the trouble that the single flow controller needs often to change dry cell.
Claims (2)
1. the solar water heater controller of a DC-AC two-use, comprise that water-temperature water-level detects control circuit, controller housing (1), display screen (2), function setting key (3), it is characterized in that: aforesaid solar water heater controller also comprises dry cell storehouse (4) and AC power cord (5), AC power connects the operating circuit that AC-DC adapter and dc source are connected controller jointly, between dc source and controller operating circuit, be connected with auto switching device K, auto switching device K is in open position when Alternating Current Power Supply, when outage or AC power disconnection, auto switching device K closure, controller utilizes dry cell power supply.
2. solar water heater controller according to claim 1 is characterized in that: the power line that connects AC power is a plug type.
