Air-source water heater also claims " air source hot pump water heater ", and its pyrogen processed reason is that the low-temperature heat quantity in air is absorbed, gasify through fluorine medium, then by pressure build up after compressor compresses, then feedwater heating is transformed by interchanger, with the high temperature heat after compressing to heat water temperature. Air-source water heater overcomes solar water heater and relies on sunlight to adopt heat and install the shortcoming of inconvenience, and avoid electric water heater electric leakage, gas heater likely explodes and poisoning danger.
Air-source water heater in existing market carries out operating and controlling mainly through manual operator, namely when user needs to use hot water, is started shooting by manual operator and sets the water temperature that need to be heated to. After water-heater heats water to the water temperature of described setting, user brings into use hot water. After using hot water to terminate, shut down by manual operator. This kind of control method is simple, but on the one hand, user cannot accurately know when water-heater can heat water to the water temperature of described setting, and by the time needs to start shooting during use hot water cannot use hot water immediately again, thus makes troubles to user. On the other hand, if make water-heater be in open state or be in open state for a long time always, then water-heater in insulating process owing to hot water heat constantly dissipates, it is necessary to repeatedly heat, so that water-heater is not energy-conservation.

The above-mentioned t calculatednPreferably can inform user as required, such as, to be displayed in display panel or the otherwise mode such as such as voice of described air-source water heater, so that user understands when can use hot water.
In addition, further, described control device comprises input unit 6 further, and user can utilize input unit input about the information of above-mentioned atmospheric environment temperature, and further, user can also take over, by this input unit 6 input table, the preset time t that the time of hot water is wished to use in family for uses, so that described air-source water heater heated with reference to this default time.
Due under normal circumstances, in one day, the temperature higher period is between 12:00 to 16:00, therefore, preferably, user preferably can carry out reservation before 12 o'clock and arrange, and after being engraved in when arranging reservation water at 16, that so can avoid described air-source water heater operates in the moment that in one day, temperature is lower, thus better energy-conservation.
Further preferably, if it is t that user sets the initial time of described default time0, then, before whether the relation of described judging unit 3 between the envrionment temperature judging environment residing for described atmospheric environment temperature and described air-source water heater meets the predetermined condition that start runs, described preset time t is judgedsWith tnBetween relation whether meet t0+tn≤tsIf meeting, whether the relation continuing to judge between the envrionment temperature of environment residing for described atmospheric environment temperature and described air-source water heater meets the predetermined condition started shooting and run; If not meeting t0+tn≤ts, then directly export start-up command and the start of described air-source water heater run.
Specifically, the preset time t that user is utilizing described input unit 6 setting table requisition family to wish to use the time of hot watersTime, judging unit obtains this and presets actual tsWhile automatically record this moment time as initial time t0.Judging unit 3 obtains its time t that water is heated to target water temperature needs calculated from calculating unit 5 simultaneously simultaneouslyn, and then judge whether to meet t0+tn≤ts. If judged result meets this inequality, then judging unit 3 judges whether the relation between the envrionment temperature of environment residing for described atmospheric environment temperature and described air-source water heater meets the predetermined condition of start operation further, namely Te >=Tmin+ (Tmax-Tmin) * k whether is met, the words being then send described start-up command, and described air-source water heater is started shooting operation accordingly; No words continue to detect said temperature data in real time and judge said temperature relation. If judged result shows not meet t0+tn≤ts, then show that user wishes that the time of use water has been less than the time of these needs, now judging unit 3 directly sends described start-up command, and described air-source water heater is started shooting operation accordingly, to be heated by water as early as possible, meets user's water demand.

In addition, further, described control method comprises input step further, and user can input the information about above-mentioned atmospheric environment temperature, and further, user can also take over the preset time t that the time of hot water is wished to use in family for use by input tables, so that described air-source water heater heated with reference to this default time.
Further preferably, if it is t that user sets the moment of described default time0, then, in described determining step, the relation between the envrionment temperature judging environment residing for described atmospheric environment temperature and described air-source water heater also judges described preset time t before whether meeting the predetermined condition that start runssWith tnBetween relation whether meet t0+tn≤tsIf meeting, whether the relation continuing to judge between the envrionment temperature of environment residing for described atmospheric environment temperature and described air-source water heater meets the predetermined condition started shooting and run; If not meeting t0+tn≤ts, then directly export start-up command and the start of described air-source water heater run.
Fig. 3 is the schema preferably realizing described control method specific embodiment according to the present invention one. As shown in Figure 3, first in step S301, temperature acquiring unit 1 obtains described first environment temperature and second environment temperature, namely, use described air-source water heater area local same day atmospheric environment temperature and described air-source water heater residing for the envrionment temperature of environment, and the initial water temperature of the water in water tank; User utilizes input unit 6 to set the preset time t characterizing and wishing to use the time of hot water simultaneouslys. In step s 302, setting unit 2 sets described target water temperature according to first environment temperature and second environment temperature, and calculate unit 5 according to the same day atmospheric environment temperature, initial water temperature, water tank capacity and target water temperature, calculate the time t reaching this target water temperature and needingn. In step S303, judging unit 3 judges described preset time tsWith tnBetween relation whether meet t0+tn≤tsThe words being then proceed to step S304, and whether the relation continued between the lowest temperature Tmin that judges in the envrionment temperature Te of environment residing for described air-source water heater and atmospheric environment temperature and highest temperature Tmax meets Te >=Tmin+ (Tmax-Tmin) * k. The words being then export start-up command, control the start of described air-source water heater accordingly in step S305 breaker in middle machine unit 4 and run. On the other hand, if judged result is no in step S303, then judging unit 3 directly exports start-up command, and start-up unit controls the start operation of described air-source water heater in step S305. In step s 304, if it is determined that result is no, then returns step S303 and re-start judgement.These are only that the schema according to Fig. 3 is to the description of the specifically scheme sent out method of the present invention and carry out, it is necessary to explanation be that it is only exemplary.
The present invention also provides a kind of air-source water heater, and it comprises above-mentioned control device.
