Fig. 5 is an example of tables of data that is built in the inside such as ROM of indoor controller shown in Figure 2.

Fig. 2 is the general structure of one embodiment of the present of invention, in the drawings, air conditioner 1 possesses off-premises station 11, indoor set 21 and remote controller 31 etc., have the compressor 2 that inverter is driven with refrigerant pipe arrangement 9, the cross valve 3 that the control refrigerant flows, the indoor heat converter 5 that indoor fan 4 is disposed in opposite directions simultaneously, the outdoor heat converter 8 that the expansion valve 6 of control refrigerant flow and outdoor fan 7 are disposed in opposite directions couples together the freeze cycle that constitutes.

Freeze cycle is by means of the handover operation of cross valve 3, and making refrigerant is exactly the operational mode that produces cold air along solid arrow direction circulation among the figure.

And, in indoor set 21, mainly accommodate indoor electric fan 4 and indoor heat converter 5, indoor heat exchange sensor 10 with the temperature of checking this indoor heat converter 5, and off-premises station 11, in outdoor unit 12, holding freeze cycle structure members such as compressor 2, the outdoor controller 15, the driving loop 16 that also have the outdoor heat exchange sensor 13 of sensing chamber's outer heat-exchanger 8 temperature, connect receiving loop 14, micro computer etc. to constitute simultaneously.

Indoor set 21 built-in detect room temperature temperature sensor 22, detect indoor humidity humidity sensor 23, detect the indoor controller 25, serial transmission loop 26, receiving loop 27 and the display part 28 that constitute from indoor photothermal radiation sensor 24, with for example micro computer etc.

Indoor controller 25 reads each detected value from room temperature, humidity, radiation sensor 22-24 and indoor heat exchange sensor 10 these sensors, difference according to these detected values and each setting value is calculated the running frequency that determines compressor 2, and this running frequency that determines is sent to outdoor controller 15 by means of serial transmission loop 26, series connection receiving loop 14.

Remote controller 31, also as shown in Figure 3, make the operation/shutdown switch 32 of the button-type that the operation of air conditioner begins or stop, to producing the operational mode of cold air, produce the operational mode of heating installation, automatic operational mode, the push button operation change-over switch 33 that this several modes whenever can switch in regular turn by push button whenever just can step ground rises or descends by temperature, set the button-type room temperature configuration switch 34 of room temperature, setting is to the air quantity change-over switch 35 of the air output of indoor air-supply, make blow out cold and hot air shutter automatically, rotate low-angle shutter pole changer 36 discontinuously, with select still to be located on the remote controller main frame 38 with these switches 32-36 with liquid crystal display to the operational mode of the generation changes in temperature gas of setting etc. and the display part 37 of setting value at room temperature.

Also have, above-mentioned automatic operational mode is that the temperature according to room temperature and outside switches to suitable operational mode, promptly produces cold air or produce the pattern of heating installation, automatically selects the operational mode of setting room temperature and conversion air quantity on the other hand again.

And remote controller 31 is with remote controller shown in Figure 2 39, will be built in the remote controller main body 37 from the transmission loop 40 that the various control signals of this remote controller 39 are sent with infrared ray for example etc.As shown in Figure 3, the sending part 41 that sends out the infrared light that sends loop 40 is located at the side of the front end of remote controller main body 37.

Remote controller 39 is during by following operation in tandem operation/shutdown switch 32 and operation change-over switch 32, as shown in Figure 4, and the transmission loop 40 that is output as the fixed mode code signal A of the initiating signal that the fixed mode operation is begun.With this fixed mode code signal A, make freeze cycle and sensor input value and setting value at room temperature etc. irrespectively, with the forced service of predefined air-conditioning ability.Thereby, in remote controller 39, constitute the control device that fixed mode is begun.

(1) at first, see that the display part 28 of remote controller 31, the indicator lamp (not shown) that the affirmation expression is moving do not have light yellow.

(2) then, by moving change-over switch 33, switching to automatic operational mode.

(3) then, always according to operation/shutdown switch 32 and escort capable change-over switch 33.So, as shown in Figure 4, the output earlier of operation initiating signal, the indicator lamp light yellow that the expression of the display part 28 of remote controller 31 is moving, simultaneously, and after the operation initiating signal, the output of fixed mode code signal.

(4) then, with hand or what anything else be covered with the sending part 41 of remote controller 31, just the receiving loop 27 of indoor controller 25 is not received under the shading state of operation stop signal by operation/shutdown switch 32 from the sending part 41 of remote controller 31.With this, the indicator lamp that the expression of remote control display part 28 is being moved extinguishes, but moving stop signal fails to deliver to indoor controller 25, thereby freeze cycle continues with automatic operational mode operation.

(5) then under the state of operation/shutdown switch 32 of pressing (4), the light accepting part of the sending part 41 of remote controller 31, by operation change-over switch 33 facing to the receiving loop 27 of indoor set 21.

(6) operation of above-mentioned (3)-(5) was for example carried out with interior at the appointed time in 3 seconds.

With this, run action fixed mode code signal A sending part 40 superpositions from remote control system 31 in 3 seconds of two pulse types are exported at infrared ray, accepted by the light accepting part of the receiving loop 27 of indoor set 21, give indoor controller 25.

Indoor controller 25 when these two run action fixed mode code signal A were received as light in 3 seconds, makes it export for example sound of buzzer, notifies people to enter the fixed mode operation.Also have when this fixed mode operation is being carried out, during switch beyond the shutter pole changer 36 of remote controller 31, this fixed mode operation stops.When fixed mode was moved, the change of having only the shutter angle was possible.

In a word, indoor controller 25 built-in the control program shown in the flow chart of Fig. 1.Below this control program is illustrated, S1-S9 represents each step of flow chart among Fig. 1.

At first, at S1, indoor controller 25 judges whether to have received the common operational mode operation initiating signal from remote controller 31 repeatedly, at YES, when just having received the operation initiating signal, judge whether to have received run action fixed mode code signal A at S2, when YES, make for example 3 seconds timer starting at S3.

S4 in the back judges whether to receive the 2nd run action fixed mode code signal A, in No, judges repeatedly whether the timer in 3 seconds is that time is up, promptly transfers to S8 when time is up.

But, at S4, when in 3 seconds, having received two run action fixed mode code signal A, no matter setting value at room temperature how, makes freeze cycle with the fixed mode operation predefined, that the air-conditioning ability is certain.

In a word, no matter setting value at room temperature how, with the running frequency of predefined compressor 2, the setting value of the opening program of separately revolution of indoor and outdoor fan 4,7 time per units, the position that blows out the shutter of cold and hot air, expansion valve 6 makes the freeze cycle operation.Thereby, even because temperature sensor 22, the heat exchange sensor, sensors such as pressure sensor break down cause based on the operation of air conditioner of the common operational mode of setting value at room temperature operation can not the time, as long as run action is fixed mode, air conditioner just can be before the fault of sensor etc. be fixed emergency operating.

Then, at S7, judge repeatedly whether the fixedly ring off signal that can remove this fixed mode operation is transfused to.The output when press button of this fixedly ring off signal beyond shutter for example shown in Figure 3 turns to press button 36 is operated.

At S7, when fixedly ring off signal is transfused to,, transfer to operation based on the common operational mode of setting value at room temperature at S8, at S9, judge whether to move stop signal input, operation of air conditioner termination back end repeatedly.

Thereby, according to present embodiment, even cause under the situation that the operation of air conditioner based on the common operational mode of setting value at room temperature can not carry out in fault because of temperature sensor 22 sensors such as grade, so long as with the operation of the certain fixed mode of air-conditioning ability, just can make air conditioner main body emergency operating obtain repairing to the fault of this sensor etc. till.

And this fixed mode operation can be very easy to by means of the manual selecting arrangement of remote controller 31 and promptly select implement.

Again, when manually selecting the fixed mode operation, must press the operation/stop button switch 32 of remote controller 31 on one side, on one side by operation switching push button switch 33, because must be according to correct order by two press buttones, so can reduce malfunction, and can manually select the run action fixed mode with the operation of pressing the press button that remote controller 31 is provided with, therefore, needn't newly establish the dedicated button switch of manual selection fixed mode operation, thereby can seek remote controller 31 small-sized lightness simultaneously and suppress the cost rising.

Also have, in the aforementioned embodiment, a kind of situation with certain air-conditioning ability operation that preestablishes the fixed mode operation is described, but the invention is not restricted to this, for example shown in Figure 5, also can preestablish with large, medium and small three other abilities of level and carry out the fixed mode operation according to setting value at room temperature.

That is to say, as shown in Figure 5, in advance according to setting value at room temperature, set the running frequency (hertz) of compressor 2, the revolution of indoor and outdoor fan 4,7 time per units by the ability of for example big H, middle M, little L, set the position of the shutter and the cross valve 3 that blow out cold and heat air simultaneously, these (data) are stored in as tables of data among the ROM of indoor controller 25, according to the house temperature of setting, carry out the figure table look-up and extract the running frequency etc. of compressor 2, also can by this setting value operation.

According to this embodiment, when air conditioner moves with fixed mode, also can therefore can lower excessive degree of air-conditioning ability or not enough program according to the suitable selection air-conditioning of setting value at room temperature ability.

And the profound switch of the air-conditioning ability when the fixed mode operation is selected in the manual operation that also can be fit to is located in the main body of indoor set 21.At this moment, even under situation that the situation that the manual selection function of run action fixed mode of remote controller 31 breaks down or the battery of remote controller use up or the situation that does not have remote controller, the air-conditioning ability in the time of also suitably selecting to realize the fixed mode operation by means of this profound switch.Also have, the present invention is also applicable to the freeze cycle of omitting above-mentioned cross valve 3.

As mentioned above, the application's invention is provided with on remote controller and can selects to make the air conditioner main body by the fixing selecting arrangement of operational mode of the run action of predefined predetermined air-conditioning ability forced service.

Thereby, manually select fixedly operational mode by means of this selecting arrangement, with this, even the thing of sensor classes such as temperature sensor breaks down, in the time of can't carrying out according to the common operation of air conditioner of setting value at room temperature work, before the fault restoration of the thing of this sensor etc., also can be by predefined certain air-conditioning ability operation of air conditioner of meeting an urgent need.And, by means of the selecting arrangement of remote controller, can carry out this fixed mode operation easily, rapidly.Can remove the inconvenience in the prior art example from.

Again,, when manually selecting fixed mode, at least two switches must be operated simultaneously, therefore, the wrong choice fixed mode can be prevented according to the application's the 2nd invention.

According to the application's the 3rd invention, when manually selecting fixed mode, must press at least two switches repeatedly more than twice simultaneously, therefore can prevent the wrong choice fixed mode reliably.

The application's the 4th invention, when manually selecting fixed mode, the operation/shutdown switch of remote controller on one side, on one side operation operation change-over switch, must carry out a plurality of operating procedures with correct order, therefore, can reduce operating mistake, and, the switch that remote controller is provided with, can manually select fixed mode, therefore, there is no need newly to establish the fixed mode special switch of manual selection, thereby can seek to make small-sized, the lightness of remote controller simultaneously, and suppress the rising of cost.

The application's the 5th invention also can be selected the air-conditioning ability according to predefined setting value at room temperature suitably when air conditioner moves with fixed mode, thereby can reduce excessive degree of air-conditioning ability and not enough degree.

The application's the 6th invention, the change-over switch that the fixed mode several air-conditioning abilities of manual switchover are used is set on the air conditioner main body, thereby, even under the situation that the fixed mode selecting arrangement with remote controller breaks down, the air-conditioning ability in the time of also utilizing this change-over switch to select the fixed mode operation suitably.
