Embodiment

Below in conjunction with accompanying drawing a concrete embodiment of the present utility model is described.

As shown in Figure 1, the intelligent temperature time controller that provides of the utility model comprises: temperature-sensing probe, testing circuit, governor circuit, timing memory circuit, LED display circuit and keyboard input circuit;

Wherein, described testing circuit is connected with described temperature-sensing probe, described governor circuit, described LED display circuit, described keyboard input circuit and described timing memory circuit respectively;

Described governor circuit is connected with and is used to control the switchgear that heat pump is opened.

Described timing memory circuit is used to store the corresponding relation of setting-up time point and the set temperature value corresponding with described setting-up time point.

Described testing circuit comprises single-chip microcomputer.

The course of work of the intelligent temperature time controller that the utility model embodiment provides is:

(1) needs to detect the time point (setting-up time point) of water temperature and the corresponding relation of the temperature value (set temperature value) corresponding by the keyboard input circuit to timing memory circuit input with this time point; And this corresponding relation can show by the LED display of LED display circuit.

For example: as shown in table 1 according to actual needs, can set following 6 groups of corresponding relations, that is: 10n, the water temperature that the user needs during 10:00 is 30 ℃; And 20n, during 11:00, the required water temperature of user is 34; ... 60n, during 15:00, the required water temperature of user is 50.

Table 1

The concrete grammar of importing above-mentioned corresponding relation by the keyboard input circuit is: the MOEDL button that is disposed by the lower keyboard input circuit, enter the demonstration time and (comprising: interface hour, minute two parts), press the SET button, show corresponding relation sequence number 10n, press the MOOL button then, the time figure that shows begins flicker, by pressing the plus-minus button time figure is regulated, until reaching required numeral; Secondly, press the MOEDL button, the displays temperature value, by pressing the plus-minus button temperature digital is regulated,, pressed the SET key once more and forward the interface that shows 20n to until reaching required numeral, carry out same setting and get final product, all set until above-mentioned 6 groups of corresponding relations and finish, return by the SET key.

By the keyboard input circuit, also can make amendment to each parameter value (setting-up time point, set temperature value etc.) by same method.

(2) temperature-sensing probe is installed to water tank that solar thermal collector is connected in, according to the actual water temperature in the above-mentioned setting-up time point measurement water tank, and send the actual water temperature value that measures to testing circuit.

(3) after testing circuit receives the actual water temperature of temperature-sensing probe transmission, this water temperature is shown by the LED display circuit, be convenient to the user and observe; And read the current time value of storing in the timing memory circuit (also being the setting-up time value), and the set temperature value corresponding with this current time value, judge whether the actual water temperature value is higher than set temperature value, if judged result is for being, show that the actual water temperature value is higher than the water temperature of the current needs of user, then send the instruction of closing heat pump, heat pump cuts out thereby trigger governor circuit to governor circuit; If judged result shows that for not the actual water temperature value is lower than the water temperature of the current needs of user, then send the instruction that starts heat pump to governor circuit, thereby trigger governor circuit heat pump is started.
