Description

Air-conditioner with dehumidification function

Technical field

The present invention relates to a kind of air-conditioner, more particularly, relate to a kind of air-conditioner that can set a plurality of dehumidification mode of operation.

Background technology

How to refer to after air-conditioner brings into operation according to time control such as factors such as compressor rotary speed and rotation speed of fan with hereinafter term " method of operation ".For example, " method of operation " means air-conditioner and can move by the type of cooling, mode of heating or dehumidification mode, to reach the operation method of GB temperature, target humidity, target wind speed and object run time etc.

Fig. 2 represents to utilize the simple structure of kind of refrigeration cycle with the conventional air conditioner of dehumidification mode operation, and Fig. 3 represents the basic structure of this air-conditioner indoor unit.

This air-conditioner even also utilize and move in cooling identical kind of refrigeration cycle in service at the dehumidifying run duration.In other words, be discharged in condenser 102 ambient airs, be transformed into fluid (cold-producing medium) then from the high temp/high pressure coolant gas of compressor 107 heat with it.With high-pressure fluid step-down in step-down (decompression) device 103, then it is offered cooler 104.In this cooler 104, cooling medium (cold-producing medium) draw heat from its ambient air, turns back in the compressor 101 so it becomes low-pressure gas then so that evaporate.

Because it is in service to be used in dehumidifying as the identical kind of refrigeration cycle of cooling operation, so even also can be influential to room temperature at the dehumidifying run duration.In other words, in Fig. 3, the indoor humid air that utilize 104 pairs in cooler to be sucked by circulating fan 105 cool off and dehumidify.Then moisture content contained in the air is become the globule, and they are entered tank 107, so that cooling.Therefore, cooled air 108 just is recycled blower fan 106 and is blown into indoor.Like this, although the user does not wish to reduce room temperature, room temperature is reducing gradually.

Can keep the air-conditioner of temperature constant also not really general again simultaneously by controlled humidity in this field.Therefore, though, up to the present also do not have the control software of satisfied dehumidifying operation according to user's life proposition above-mentioned requirements.

JP-A-3-1036 discloses the viewpoint that is used for from the user, according to humidity, wind speed with air supply direction is selected and the method for operation of the air-conditioner of set environment.Such air-conditioner has used the multiple method of operation that is applicable to how tame user.In other words, when considering that Mr. A has his required environment, and Mr. B is when having the required environment that is different from the required environment of Mr. A true, and this air-conditioner can realize setting up the method for operation of different separately required environment.For each different methods of operation difference setting operation button, so that only select the needed method of operation by each action button by correspondence.

According to the research that the applicant carries out, the desirable living environment of housewife has nothing in common with each other.Following environment then is ideal: do not reduce room temperature when dehumidifying rainy season; Dehumidification degree and do not reduce room temperature; Utilize the dry laundry of dehumidification mode of operation; By reducing the breeding of humidity mould fungus inhibition; And by reducing humidity inhibition dewfall.In a word, these housewifves wish to improve dehumidification function strongly, so that air is carried out wholesome adjusting.

The background of the demand briefly has been listed among Fig. 4.The climatic characteristic of Japan is: rainfall in 125 days was on average arranged in 1 year, and the hot weather than vast of heaven number is arranged.Owing to these characteristics and in conjunction with following situation, just need to have improved dehumidification function more consumingly.That is to say that the nearest situation of Japan is: the Japanese house with airtight construction that makes moisture be difficult for discharging has increased; Because many housewifves are job holder, so the vacant room that door and window closes has increased.

Yet nearest many families have all had second and the 3rd air-conditioner, user's expanded range, from old man to child, have, thereby need be simple to operate, make anyone all easy-to-use air-conditioner.

Fig. 5 represents and the pairing different dehumidification mode of operation of different dehumidifying conditions that propose according to user's life style.In a word, user's needs are divided into four kinds of typical modes, i.e. " standard mode ", " laundry drying mode ", " mode of leaving home " and " suppressing the dewfall mode ".It will be appreciated that the title of these dehumidification mode of operation is to name from the content of function for convenience's sake.It should be noted that except these four kinds of modes, other various dehumidification modes all are available.In addition, multiple laundry drying mode also can be set.Four kinds of dehumidification modes mentioning have first been done temporary explanation basically.

Though had the demand of above-mentioned user to the dehumidifying operation now, conventional air conditioner is not improved according to dehumidification function as yet, this is to be put on refrigerating function and the heating function owing to people or improved emphasis.For example, conventional air conditioner running when substituting the dehumidification mode operation with the type of cooling is slim and graceful.Therefore, traditional controller speed wind-warm syndrome degree is lower, and when they turned round continuously, room temperature was fallen lowly excessively, and this is disadvantageous.Therefore, this dislikes the problem that the people of cold wind arranged or be unwilling to reduce the human needs of room temperature with regard to existing a conventional air conditioner to be not suitable for those.

In addition, for conventional air conditioner, when dehumidifying, room temperature has not desirably reduced, and promptly the reduction degree of relative humidity has reduced.When further dehumidifying, room temperature even also can reduce.Therefore, when this existed another to be reluctant to make this room temperature further to reduce when rainy season again, air-conditioner can not be with the problem of dehumidification mode operation.

With adopting dehumidifying operation aspect, the JP-A-3-1036 suggestion not only will be controlled temperature, and should control the environment that comprises wet environment as for the needs of considering the user.According to this prior art, its good operation make the user only need flicking once one of them dedicated button just can select the suitable wet environment that removes.Yet the environmental field that the air-conditioner of JP-A-3-1036 is set up is confined to the mankind.That is, JP-A-3-1036 does not expand the application of air-conditioner to each application of user's life activity, the dry operation of the laundry when being absent from the scene as the user, the dry operation in room etc., and the operation of the inhibition dewfall at night.

Therefore, disclosed air-conditioner is provided with a plurality of action buttons respectively according to the different methods of operation in above-mentioned patent application.So just make any babe in the wood, all be difficult to correctly select suitable action button as old man and child.

The specific embodiment

Now with reference to accompanying drawing several different embodiment of the present invention is described.

Fig. 6 schematically expresses the basic structure that is implemented in the kind of refrigeration cycle that dehumidifies under the situation that does not reduce room temperature in the air-conditioner of one embodiment of the invention.Label 104a and 104b represent the heat exchanger in the indoor unit, magnetic valve of label 110 expressions.It should be noted that, in the figure with Fig. 2 in identical label represent similar or identical parts, therefore omit explanation to them.

In Fig. 6, be divided into two heat exchanger 104a and 104b again as the heat exchanger of the conventional air conditioner indoor unit of cooler operation.The heat exchanger 104a and the 104b of these two segmentations are connected to each other by magnetic valve 110.In the dehumidifying running, a heat exchanger 104a who is positioned at cooling agent (cooling medium) upstream side (from the direction of arrow indication) is as radiator, and another heat exchanger 104b that is positioned at its downstream is as cooler.For above-mentioned reasons, heat exchanger 104a will refer in particular to and be " radiator ", and heat exchanger 104b will refer in particular to and be " cooler ", unless done special explanation.

Fig. 7 is a kind of profile of structure of the air-conditioner indoor unit of expression present embodiment.Among Fig. 7 with Fig. 3 in identical label be used for presentation graphs 7 identical or similar parts.

In Fig. 7, radiator 104a is positioned at the top of indoor unit, and cooler 104b is positioned at the bottom of indoor unit.A part is cooled during by cooler 104b by indoor wind 105 inhaled airs 106, makes the moisture that is included in the air 106 meet cold and condensation.So and the water droplet of formation is stored in the water droplet groove 107.So just, the air by cooler 104b is dehumidified.But because air is through supercooling, its temperature has reduced.On the other hand, the air 106 of the remainder of indoor fan 105 suctions is heated by radiator 104a the time.This hot-air part is mixed by cooler 104b cooled air with above-mentioned then.The result has heated the air by cooler 104b, and the air 108 that the reduction of the temperature of discharging from indoor unit is suppressed has become the low humid air that relative humidity reduces.

The temperature of the temperature of the wind that Fig. 8 A and 8B diagramming are sent from conventional air conditioner and the wind of from the air-conditioner of present embodiment, sending.

Suppose that the air themperature that sucks indoor unit is 27 ℃, when utilizing the cooling method of operation identical with traditional air-conditioning to dehumidify operation, as shown in Fig. 8 A, the temperature of the wind of sending from indoor unit is 17 ℃ so.On the contrary, according to present embodiment, shown in Fig. 8 B, the temperature of the wind of sending from indoor unit is 24 ℃.Such just as explained above, according to present embodiment, the reduction of wind pushing temperature can be inhibited, and makes because of wind pushing temperature reduces the problem of being brought and has obtained solution.

It should be noted that though wind pushing temperature is selected 24 ℃, this air themperature can improve, or is reduced to below 24 ℃.In order to improve wind pushing temperature, a kind of adoptable method is the rotating speed that reduces the blower fan of use in the indoor unit.In the method, the radiator that has used in the indoor unit owing to used heat exchanger in the outdoor unit has reduced heat radiation has increased heat radiation, and therefore the temperature of the wind of sending from indoor unit has just improved.The result has realized so-called " accurate heated type dehumidifying operation ".Similarly,, can reduce the temperature of the wind of from indoor unit, sending, so can realize so-called " accurate cooled dehumidifying operation " by improving the rotating speed of the fan motor that uses in the indoor unit.

In addition, microcomputer 3 comprises a CPU10 and a storage device 11 that is used to store the data relevant with temperature, humidity, wind speed and running time etc., and this CPU and storage device 11 are according to being set by the dehumidification mode of operation of remote controller 2 indications.In this case, can specify four kinds of dehumidification modes.Can utilize at least a and operating time in temperature, humidity and the air speed data to combine to specify a kind of mode in these dehumidification mode of operation.It should be noted that the combination of above-mentioned data will be called " dehumidification mode of operation information " hereinafter.Should also be noted that any dehumidification mode of operation except that above-mentioned four kinds of dehumidification mode of operation all can specify.

Remote controller 2 mainly is made of the microcomputer 13 of the total operation that is used to control this remote controller.Controller 2 also comprise can both be circularly when a user handles this remote controller 2 at every turn and can both be circularly when sequentially selecting the dehumidifying button 14 of four kinds of dehumidification mode of operation, operation that is used to move/stop air-conditioner/stop ammonium turning round 15 and users to handle this remote controller 2 at every turn and sequentially change multiple setting-up time (hour) timer button 16.This remote controller 2 also comprises the display unit 17 of a content that is used to show the method for operation that sets, a transfer circuit 18 and a battery 19 that is used for providing electric energy to remote controller 2 that is used for transmitting to the receiving circuit 4 of main body 1 signals.

As hereinafter described, when at refrigeration (cooling) run duration, or the heating run duration is when handling dehumidifying button 14, and the method for operation of air-conditioner changes over dehumidifying and moves.In addition, if between the air-conditioner down period, handle dehumidifying button 14, can start the dehumidifying operation.Microcomputer 13 is made of CPU20 and storage device 21.Storage device 21 is to be used for the stationary storage dehumidification mode of operation information A i corresponding respectively with four kinds of dehumidification mode of operation of preliminary election within it by one, Bi, Ci, the ROM22 of Di and one are used for storing that the storage device of these dehumidification mode of operation information constitutes with rewriteeing, and for example storage device in this case is RAM23.Should also be noted that when five kinds of needs or more kinds of dehumidification mode of operation, with corresponding warm method of operation Ei, the Fi of removing of the dehumidification mode of operation of these increases ...Can further be stored among this ROM22.

In the present embodiment, selected four kinds of dehumidification mode of operation explaining above are " standard mode " shown in Fig. 5, " laundry mode ", " mode of leaving home " and " suppressing the dewfall mode ".

Fig. 9 and Figure 10 are the flow charts that is used to explain the control operation of remote controller 2 and main body 1.At first explain the control operation of remote controller 2 with reference to Fig. 9.

After battery 19 installed, CPU20 and transfer circuit 18 preset, and read in the ROM22 that is stored in memory 21 so that be sent to dehumidification mode of operation information A i in the RAM23, Bi, Ci, Di.With dehumidification mode of operation information A i, Bi, Ci, Di be as dehumidification mode of operation information A e, Be, and Ce, De write (step 30) among the RAM23.

It will be appreciated that,, do not carry out following control operation when battery 19 discharges into when being lower than predetermined volumes.In this case, when replacing the most used batteries 19 of power consumption with new battery, presetting in carry out step 30 once more.Display unit 17 can show the current capacity of the battery 19 that is lower than predetermined volumes.

Next step then monitors (step 31) to the input operation of button.After the input operation of button is carried out, judge which kind of button (step 32) operated be.

When the button of handling is timer button 16, check whether main body 1 is in running status (step 33).When judging that main body 1 is not moved, process operation turns back to monitor procedure (step 31).On the contrary, when judging that main body 1 is in running status, then detect whether carried out timer operation (step 34) with another kind of detection mode.

Should be noted that " timer operation " refers to the operating time is those operations of being scheduled to, under these modes of operation, can carry out various operations, as heating, cooling, dehumidifying operation etc.In addition, optional majority kind running time during timer operation.

When judging that in step 34 the current method of operation is not the timer operation, when being moved, the initial value that is used to specify running time is sent to main body 1 (step 35) by transfer circuit 18 with information.On the contrary, when judging that the current method of operation is the timer operation, should be sent to main body 1 (step 36) by transfer circuit 18 in information command running time of being appointed as current setting running time subsequently.So just be transformed on the running time of appointment the running time with air-conditioner.

When handling dehumidifying button 14 (step 32), judge whether main body 1 is in running status (step 37).When judging that main body 1 is when not being in running status, to move initiating signal and be sent to main body 1 (step 38) by transfer circuit 18, will show (step 39) with the content of the corresponding to dehumidification mode of operation of content of the LCDs that is used in the display unit 17 in the remote controller 2 then with a kind of dehumidification mode of operation information of storage in RAM23 (Fig. 1).When judging that main body 1 is in the running status of step 37, check that whether main body 1 is with dehumidification mode of operation operation (step 40).When judging that main body 1 is not moved under dehumidification mode of operation, process operation proceeds to step 38.On the contrary, when judging that main body 1 is moved under dehumidification mode of operation, read dehumidification mode of operation information from RAM23, this information is used to specify dehumidification mode of operation, and this mode is subsequently with the dehumidification mode of operation of carrying out.The dehumidification mode of operation information of reading is sent to main body 1 (step 41) from transmission circuit 18.Process operation proceeds to step 39 then.

When operation and control/stop button 15 (step 32) when moving, will move stop signal and be sent to main body 1 (step 42) from transfer circuit 18.Therefore, this air-conditioner can stop any method of operation.

It should be noted that, when main body 1 stop and operation and control/during stop button, just send out that the condition of setting with remote controller is correspondingly relevantly for example operated automatically, heated, the operation initiating signal and the method for operation information of dehumidifying, cooling or pushing wind manipulation etc.

When handling as during button such as dehumidifying button 14, operation/stop button 15 and timer button 16, CPU20 storage and the button information corresponding of handling, and according to the state of the information continuous monitoring main body 1 of storage.For example, after air-conditioner installs and connect circuit 12, carry out primary operation/stop button 15 operations, make information (running mark) instruction of main body under running status pass to CPU20.When each operation and control/stop button 15, air-conditioner alternately stops and moving subsequently.Respond this state alternately, running mark also alternately discharges and set.According to running mark, decision making in step 33 and 37.

When handling dehumidifying button 14, if air-conditioner is in running status, then the method for operation of this air-conditioner is transformed into the dehumidifying operation, and the information (dehumidifying sign) that will be used to indicate main body 1 to be in the dehumidifying running status is passed to PU20.Certainly, at this moment also set running mark.When being in halted state, air-conditioner handles dehumidifying button 14, air-conditioner across-the-line starting under the dehumidifying running status.Simultaneously, running mark and dehumidifying sign are all passed to CPU20.Decision making in step 40 according to this dehumidifying sign.Even handle dehumidifying button 14 when air-conditioner is in dehumidification mode, running mark and dehumidifying sign also all are in set condition.If go back operation and control/stop button 15 when air-conditioner is in the dehumidifying running status, then air-conditioner is out of service, and running mark and dehumidifying sign are all discharged.

In addition, when running mark is set and air-conditioner when moving under above-mentioned any method of operation, if handle timer button 16, then begin the timer operation, the information (timer sign) that also will be used to indicate main body to move under the timer mode is simultaneously passed to PU20.Even handle timer button 16 at the timer running, the timer sign also keeps set condition.When at timer run duration operation and control/stop button 15, air-conditioner is out of service, discharges the timer sign of setting then.According to this timer sign, decision making in step 34.

The control operation of main body 1 is described with reference to Figure 10 below.

When linking to each other with power supply 12 so that can when main body is powered, microcomputer 3 be preset with main body 1.Just CPU10 is preset, the content of memory 11 is eliminated, and receiving circuit 4 is preset (step 50).Whether monitoring exports received signal (step 51) from receiving circuit 4.When received signal occurred, which kind of received signal (step 52) what judge reception was.

When judge received signal with by operation and control/stop button 15 resulting operation stop signals when consistent, whether the inspection air-conditioner is in running status (step 53).If air-conditioner is in running status, then stop the operation (step 54) of this air-conditioner, process operation turns back to step 51 then.

When judging that in step 52 received signal and operation initiating signal and method of operation information (being above-mentioned dehumidification mode of operation information and the information that is used to specify the cooling operation) are consistent, whether the judgement air-conditioner is in running status (step 55).If air-conditioner is not in running status, so the room temperature detector 5 in being used for main body 1, outdoor temperature detector 5 ' and moisture detector 6 read temperature and humidity (step 56).Then, read method of operation information (receiving) step 57 that constitutes by data with the operation initiating signal that from receiving circuit 4, receives as design temperature, and with these method of operation information write storage device 11 (steps 58).Subsequently, judge selection any method of operation (step 59) according to the memory contents of this method of operation information.According to this result of determination, starting compressor motor 9, indoor fan motor 7 and outdoor fan motor 8 (step 60).

For example, when received signal and by handling operation initiating signal that dehumidifying button 14 produces and dehumidification mode of operation information when consistent, the method for operation information of reception is consistent with the dehumidification mode information that is made of the various data relevant with design temperature, setting humidity, wind speed setting and setting running time etc.Read this method of operation information (step 57), then write storage device 11 (step 58).Whether the method for operation of checking appointment consistent with dehumidification mode of operation, and the method for operation of further checking appointment whether with above-mentioned four kinds of dehumidification mode of operation in any consistent.(step 59).

After this, from room temperature detector 5 and moisture detector 6, read room temperature and humidity (step 62).Calculate the rotating speed (step 63) of air compressor motor 9, indoor fan motor 7 and outdoor fan motor 8 according to the difference between these room temperatures, humidity, design temperature and the setting humidity.CPU indicates the rotating speed rotation (step 64) to calculate of these air compressor motors 9, indoor fan motor 7 and outdoor fan motor 8.Then, process is handled and is turned back to step 51, and CPU waits for received signal in this step.

It should be noted that air compressor motor 9, indoor fan motor 7 and outdoor fan motor 8 and rotating speed can utilize among the above-mentioned JP-A-3-1036 disclosed method to determine.

When from receiving circuit 4, receiving operation initiating signal and dehumidification mode of operation information (step 51 and 52), if judge that air-conditioner is in running status (step 55), then carry out with step 57 to the similar process operation of the process operation of 59 (steps 61).Process operation proceeds to step 62 then, proceeds to 64 from step 62 again.Process steps turns back to step 51 then.

As mentioned above, after just having selected dehumidification mode of operation and having brought into operation, from room temperature detector 5 and moisture detector 6, read the temperature/humidity data of operation at interval with preset time.

When step 52 judges that received signal is consistent with the timer signal that produces by manipulation timing button 16, change be stored in the memory 11 running time data content (step 65), carry out process operation in step 62 to 64 then, after this process operation turns back to step 51.

It should be noted that when received signal not occurring in the running, in step 51,62,63 and 64 repeatedly carry out one group of process operation, so that continue the identical method of operation.

As mentioned above, operation initiating signal and dehumidification mode of operation information is dehumidifying button 14 transmission by handling remote controller 2 only, so that can begin the dehumidifying operation and select dehumidification mode of operation.Then, when handling dehumidifying button 14 during air-conditioner is out of service, according to operation initiating signal that sends from remote controller 2 and dehumidification mode of operation information, the method for operation that air-conditioner is determined according to this dehumidification mode of operation information begins dehumidifying fortune.When handling dehumidifying button 14 at the air-conditioner run duration, air-conditioner only responds the dehumidification mode of operation of sending from remote controller 2, and is set to the method for operation of determining according to this dehumidification mode of operation information.

Here CPU20 reads dehumidification mode of operation information A e, Be, Ce, De circularly and sequentially from RAM23 when each manipulation dehumidifies button 14, and sends the mode information that reads to main body 1.

Figure 11 illustrates an example of dehumidification mode of operation information.For with each dehumidification mode of operation operating air conditioner, press the dehumidifying button of one or many remote controller, up to demonstrating required display mode, and will send the main body 1 (step 31 of Fig. 9 from RAM23 to by transfer circuit 18 with the corresponding dehumidification mode of operation information of the required method of operation, 32,37,38,39).Main body 1 receives operation initiating signal and method of operation information signal by receiving circuit, reads the kind of temperature and humidity to judge that dehumidifying moves from testing circuit, and the operation of beginning air compressor motor, indoor fan motor and outdoor fan motor.At this moment, poor according between room temperature, humidity and preset value and the read value, when room temperature was higher than preset value, the method for operation was transformed into " accurate cooling and dehumidifying mode ".On the contrary, when room temperature was lower than preset value, the method for operation was transformed into " accurate heating and dehumidification mode ".So just, can realize a home from home.In addition,, select cool cycles or heat cycles, stop the dehumidifying circulation simultaneously, to realize a home from home when room temperature is relevant with preset value when very big.

Stop air-conditioner with the situation of resetting the dehumidifying operation after the dehumidification mode of operation operation once more under, in air-conditioner process out of service, CPU20 store air-conditioner before just out of service the data of pass dehumidification mode of operation.When the dehumidifying operation is reset, will store the corresponding to dehumidification mode of operation information of dehumidification mode of operation with this and be transferred to main body 1 with the operation initiating signal.As a result, the dehumidification mode of operation of resetting is consistent with the dehumidification mode of operation before air-conditioner has just stopped.For example, can adopt a certain specific dehumidification mode of operation (as utilizing the dehumidification mode of operation of dehumidifying motion mode information A e) as the dehumidification mode of operation reset.In addition, can adopt air-conditioner dehumidification mode of operation before just out of service in the selected afterwards dehumidification mode of operation.After resetting the dehumidifying operation, all conversion removed the warm method of operation according to said sequence when each manipulation dehumidified button 14.

When replacing battery 19 with new battery, because remote controller 2 presets as stated above, the dehumidifying operation is carried out with specific dehumidification mode of operation (as the mode that is limited by dehumidification mode of operation information A e).All conversion dehumidification mode of operation when then, each manipulation dehumidifies button 14.

Owing in the air-conditioner running, change running time, therefore can select to be appropriate to the optimum operation time of service condition at an easy rate by handling timer button 16.

It should be noted that, though in this embodiment the operating means of air-conditioner as remote controller 2 like that and main body be arranged in 1 minute, this operating means also can be assemblied in the main body 1 integrally with main body 1.In this case, can reach the effect similar with the foregoing description.But transfer circuit 18 and receiving circuit 4 have just no longer needed.Power supply 12 can be used as the power supply of operating means.In addition, can save need not for battery 19.It is shared that microcomputer 3 can be used as the microcomputer 13 of main body.

It should be noted that though use button to operate, the present invention is not limited to this, but also can adopt other operating means to replace this push button operating means in the operating means of present embodiment.

Figure 11 expresses some examples of dehumidification mode of operation information particularly.

Express foregoing four kinds of dehumidification mode of operation in the figure, i.e. " standard mode ", " laundry drying mode-I ", " mode of leaving home " and " suppressing the dewfall mode ".In addition, also show " balanced way " and " laundry drying mode-II ".With design temperature, set at least a parameter and the dehumidification mode of operation information of setting the formation variety of way that combines running time in humidity and the wind speed setting.For each parameter of every kind of dehumidification mode of operation is selected optimum value, and these optimum values can be set at initial value.It should be noted that and to select arbitrarily the running time in the initial value, or the pre-defined rule that can combine according to the timer function with timer button 16 is selected.

Circulation selecting sequence when Figure 12 diagramming goes out the dehumidifying button 14 (Fig. 1) of the four kinds of dehumidification mode of operation of the each manipulation shown in Figure 11 is also in each demonstration information that demonstrates a kind of method of operation when selecting dehumidification mode of operation on the LCDs (Fig. 1) in display unit 17.It should be noted that according to investigation, determine selecting sequence by the order that reduces frequency of utilization (that is what, utilization rate was the highest classifies first as) to the user.For at least two kinds of dehumidification mode of operation of Figure 11, can replace laundry drying mode-I of Figure 12 with laundry drying mode-II.In addition, the interior optional position of selection circulation that dual modes such as balanced way and laundry drying mode-II can be inserted Figure 12.

Figure 13 represents can be by the running time (Fig. 1) and the setting order of timer button 16 settings.

As shown in figure 11, the initial value of the running time of dehumidification mode of operation has nothing in common with each other.Can change running time (as shown in figure 13) by handling timer button 16.During each operation timer button 16, selecting sequence is by 1,2,3,4 and 5 and order change circularly to next running time from the predetermined running time.Can simplify like this and select operation.It should be noted that the numerical value in each dehumidification mode of operation obtains from publication and experimental data.Should also be noted that " continuously (low humidity) " under " design temperature " of Figure 11 refers to the parameter of setting humidity and do not set.Similar with it, " continuously " in " running time " refers to the parameter of setting running time and do not set.Obviously, these parameters can be set.

Figure 14 is the plane of an instantiation of expression remote controller 2 outward appearances shown in Figure 1.In the figure, label 14a is that dehumidifying shows, 16a is that timer shows, 16b is the demonstration of timer shut-in time, the 72nd, and lid, the 82nd, room temperature control button, 82a are that room temperature shows.Among the figure after Figure 14 with Figure 14 before figure in identical label represent same or analogous parts.

In Figure 14, display unit 17 and lid 72 are located on the surface of remote controller 2.Dehumidifying button 14, operation/stop button 15, timer button 16 and room temperature control button 82 are located on the surface of this lid 72.Because these buttons are provided in a side of on the surface of this lid 72, they just can be handled these buttons and have improved operating characteristics thereby the user only needs flicking.

When each manipulation (pushing) dehumidifying button 14, dehumidification mode of operation by standard mode → laundry drying mode → mode of leaving home → inhibition dewfall mode again to the sequential loop variation of standard mode.Along with the variation of endless form, be presented in the various image instructions of the content of the dehumidifying shown in Figure 13 operation on the display part 14a on the LCDs of display unit 17.

Figure 15 demonstrates the arrangement examples of the displaying contents on LCDs 17.Mode of operation according to selecting with dehumidifying button 14 only is presented at associated displaying contents on the LCDs.This idea that shows with figure is given everyone, provides convenience as old man and child's operation.

Explain the content of each dehumidification mode of operation below with reference to Figure 11.

When under the situation that does not reduce temperature, dehumidifying operation, use standard mode corresponding to dehumidification mode of operation.Theing contents are as follows of this dehumidification mode of operation.When pressing dehumidifying during button 14, if the temperature range of room temperature is during the operation starting 〉=10 ℃ and≤28 ℃ between, the design temperature during the operation starting is chosen in room temperature.If the room temperature during the operation beginning is lower than 10 ℃, then design temperature is chosen as 10 ℃.When room temperature was higher than 28 ℃, design temperature was chosen as 28 ℃.When keeping this design temperature, make humidity be reduced to about 50%.

In standard mode, room temperature is lower than 10 ℃ when beginning if move, and some user may think that from comfortable viewpoint the low limit value of operation of air conditioner should be 15 ℃.But, the scope of considering comfortableness all is different for everyone, the user can remedy the deficiency of comfortableness by the clothes amount that increase and decrease is worn, therefore the low limit value with operation of air conditioner is chosen in 10 ℃, if and were lower than 10 ℃ in the room temperature in when beginning operation, would then just select 10 ℃ as design temperature.On the other hand, when temperature is too high, in the time of can not alleviating comfortableness not enough by the control amount of wearing the clothes, higher limit is chosen in 28 ℃.If the room temperature when bringing into operation is higher than 28 ℃, then be set at design temperature with 28 ℃.According to the comfortableness aspect, humidity must be lower than 60%, and from the energy savings aspect, humidity preferably is higher than 40%.In this embodiment, humidity is set at 50%.It should be noted that, by control cabinl pulpit temperature control button 82, this design temperature can be controlled in above-mentioned scope (be room temperature be equal to or higher than 10 ℃ and be equal to or less than 28 ℃) ± 3 °.As a result, in above-mentioned scope, any temperature in design temperature can be located at from 7 ℃ to 31 ℃.As for wind speed, setting low wind speed is the initial setting wind speed.But also can select other wind speed mode, as high wind speed, low wind speed and very low velocity etc.In addition, for running time, can set various running times (as shown in figure 14) by handling timer button 16.

As can be seen, the dehumidifying operation according to standard mode can not reduce room temperature, even in moist and terribly cold season, for example the rainy season in the early spring, spring and autumn can both reduce humidity, so that can set up comfortable environment from above-mentioned explanation.As everyone knows, under the identical condition of temperature, when humidity was low, moisture evaporated from human body easily, can make the people feel nice and cool like this.Therefore, in summer, those want to avoid the people who suffers from cold to substitute the type of cooling with this standard mode.

The air-conditioner that Figure 16 A and 16B diagramming go out present embodiment is required measured data and the conventional air conditioner situation that required measured data is compared with the cooling method of operation operation that is used to dehumidify the time when moving with the standard dehumidification mode.Measuring condition is as follows: Western-style room is of a size of 3.6m * 3.6m, two people is arranged in the room, and when air-conditioner brought into operation, outdoor temperature was 24 ℃, and outside relative humidity is 80%, and indoor temperature is 24 ℃, and indoor relative humidity is 80%.

Find out that from Figure 16 A and 16B the air-conditioner of present embodiment is by predetermined dehumidification mode of operation operation.In service in traditional dehumidifying, relative humidity is up to about 70%, and temperature is reduced to about 22 °.Yet according to the standard dehumidifying operation of present embodiment, relative humidity is reduced to about 50%, and temperature remains on about 24 ℃, i.e. room temperature when the operation starting.

Balanced way is the interior dehumidification mode of operation that dehumidifying is proceeded to desired degree of a kind of scope that the imperceptible temperature of indoor people is reduced.The operation of this balanced way thes contents are as follows.When flicking dehumidifying button 14 is selected balanced ways, be room temperature+2 ℃ if room temperature in 10 ℃ to 24 ℃ scope, is then selected design temperature.Even this is in order to compensate humidity reduction of caused sensible temperature when low under uniform temp when higher with humidity (compare).Can keep comfortableness like this.But when temperature is higher, in addition under low humidity sensible heats all.Therefore, when room temperature was equal to or higher than 24 ℃, design temperature was set at the temperature identical with room temperature.When temperature was equal to or higher than 28 ℃, design temperature was set at 28 ℃, was about to 28 ℃ as higher limit, to keep comfortableness.For above-mentioned reasons, humidity preferably is chosen between 40 to 60%.In this case, humidity is set at 50%.

Drying mode-I is corresponding with the method for operation of being utilized at the indoor seasoning laundry in laundry.When pressing dehumidifying button 14, be between 10 ℃ to 28 ℃ if move the temperature range of room temperature when starting, the design temperature during the operation starting is chosen in room temperature.If the room temperature during the operation beginning is lower than 10 °, then sets room temperature and be chosen as 10 ℃.When room temperature was higher than 28 ℃, design temperature was chosen as 28 ℃.When keeping this design temperature, make air-conditioner move 3 hours continuously.In this case, answer controlled humidity, make it to drop to low as much as possible.In initial setting operation, should set wind speed higher.

Because supposition has man-hour to use laundry drying mode-I indoor, so that the setting operation of temperature should be with standard mode is identical.But can select high wind speed so that improve moisture removal, and the air-conditioner continuously-running, reached for example 3 hours (or cold operation) up to dehumidifying.These 3 hours is to be used for the required typical time cycle of dry 3kg laundry, but should the time changes with the different of amount, material and other factors of laundry.

It should be noted that, similar to standard mode, by control cabinl pulpit temperature control button 82, this design temperature can be controlled in above-mentioned scope (be room temperature be equal to or higher than 10 ℃ and be equal to or less than 28 ℃) ± 3 ℃.Therefore, any temperature in 7 ℃ to 31 ℃ scopes all can be set at design temperature.As for wind speed, high wind speed can be set at the initial setting wind speed.But also can select other wind speed, for example low wind speed is as the initial setting wind speed.In addition, can set various running time by handling 16 (as shown in figure 13) of timer button.Like this, just can decide running time according to the amount of laundry.

As mentioned above, the dehumidifying operation is carried out with this laundry drying mode-I, so the user can be away from home in the laundry drying.It should be noted that,, therefore can reach higher dehumidifying effect (equaling four groups of dehumidifying effects) by the RD-569LD type dehumidifier of Hitachi company manufacturing owing to adopt the circulation method of radiating as dehumidification mode.This air-conditioner is characterised in that, under the situation that does not reduce room temperature, but laundry rapid draing, thus and the moisture of laundry can not stayed within.Therefore, indoor condition as snug as a bug in a rug, even the clothing that also can dry be washed under the situation of user in the room.

Figure 17 A, the border measurement data that 17B and Figure 18 A, 18B diagramming go out is required during with the laundry drying mode of dehumidifying operation-I operation when the air-conditioner of this embodiment, represent with solid line with work as conventional air conditioner and move the result who compares with dry laundry actual measurement data required, that dot in the cooling mode.To provide measuring condition below.The amount of laundry is 3kg, this equal one three mouthfuls other common washing loads.In Figure 17 A and 17B, the size in Western-style room is about 3.6m * 3.6m, and unmanned in the room, outdoor temperature is 24 ℃, and outside relative humidity is 80%, and the room temperature during the beginning operation of air conditioner is 24 ℃, and indoor relative humidity is 80%.In Figure 18 A and 18B, the size in Western-style room is about 3.6m * 3.6m, and unmanned in the room, outdoor temperature is 18 ℃, and outside relative humidity is 80%, and the room temperature during the beginning operation of air conditioner is 24 ℃, and indoor relative humidity is 70%.

From Figure 17 A, 17B and Figure 18 A can obviously find out among the 18B, under the situation of present embodiment, the weight of laundry was about 4.2kg when laundry operations had just finished, back 3 hours of dehumidifying operation beginning, laundry is reduced to 3kg, and this equals laundry operations and carries out weight before.This shows that clothing has reached the degree that is sufficient to.By contrast, under the situation of using conventional air conditioner, even clothing can't parch after 4 and a half hours.Indoor humidity is 70 to 80% when operation of air conditioner begins.Compare with conventional air conditioner, humidity can be fallen very lowly.

As mentioned above, if desired, can dehumidify with the laundry drying mode by this embodiment, compare with the dry operation of the laundry of carrying out with the type of cooling or mode of heating, this mode can make the very fast drying of laundry.

Drying mode-I compares with laundry, and laundry drying mode-II is a kind of mode of more paying attention to dry laundry.For the rapid draing laundry, when air-conditioner brings into operation with the room temperature that is lower than 18 ℃, design temperature is decided to be 18 ℃.At this moment, though set low humidity (or in setting-up time operation) continuously in a manner described, this mode also can reach the drying effect of expection better, makes humidity be set to 50% and can not carry out excessive dehumidifying operation.On the contrary, when medial humidity is 65%, can reach similar effect.In addition, design temperature can arrive ± 3 ℃ 18 ℃ to 28 ℃ temperature range inner control.

Figure 19 A and 19B are illustrated in laundry drying mode-II and dehumidify when operation the approximate data of the indoor humidity of actual measurement and the weight of laundry.As measuring condition, the weight of drying is 3kg, and outdoor temperature is 1 ℃, and outside relative humidity is 70%, and the room temperature during the operation spending is 23 ℃, and indoor relative humidity is 40%.

Can find out obviously that from the example of Figure 19 B the weight of laundry is approximately 4.2kg when laundry operations just begins, operation beginning after 3 hours weight be reduced to about 3kg, this equals the weight of laundry operations before carrying out.Therefore, clothing can become be equivalent to dry.It should be noted that, at run duration, in the scope of room temperature between 15 ℃ and 20 ℃.

The mode of leaving home be a kind of when indoor humidity remain on about 50% the time, even in the date that the user is away from home, also can suppress the method for operation of the breeding of flat lice and mould.When select this leaving home during mode by flicking dehumidifying button 14, the outdoor temperature when design temperature is set to the operation beginning, and the operation that dehumidifies continuously are 50% with the maintenance indoor relative humidity.Initial wind speed is fixed on the low wind speed.Should notice that when room temperature is lower than 1 ℃ this dehumidifying operation of leaving home will be interrupted.When indoor humidity remains on 40 to 60% (these are the scopes that can suppress flat lice in house and mold propagates), effective especially to the breeding that suppresses flat lice in house and mould, thus can keep indoor environment at kilter.

Owing to only just should consider indoor humidity in the mode of leaving home, the outdoor temperature in the time of therefore will moving beginning is set at indoor temperature, and reduces to utilize the operation of thermic load.During the low-temperature condition that dehumidification rate reduces, stop the dehumidifying operation, so that energy efficient.

At this embodiment, this temperature is chosen to be 1 ℃.

Recently, because sealing is all made in the house, the humidity in room will increase when the house is closed.This also can cause the breeding of flat lice in house and mould.But when air-conditioner moves in the mode of leaving home, can suppress to cause these flat lices of specificity and asthma disease and the breeding of mould.Thereby can set up the indoor environment of health.Owing at this moment design temperature is adjusted to outdoor temperature, does not just need extra energy and can realize comparatively economic dehumidifying operation.

Figure 20 diagramming goes out the situation of change of humidity and measured data during the air-conditioner of present embodiment moves 4 hours in the mode of leaving home, and also expresses flat lice and the viable humidity range of mould simultaneously.Provide measuring condition at this time below.The size in Western-style room is approximately 3.6m * 3.6m, and unmanned in the room, outside relative humidity is 80%, and room temperature is 24 ℃ when air-conditioner moves, and indoor relative humidity is 80%.

As can be seen from Figure 20, the dehumidifying operation of leaving home begins that relative humidity reaches 60% after about 30 minutes, and relative humidity reaches 50% after about one hour then, and this is the scope that can suppress flat lice and mold propagates, and this will bring great advantage.From this aspect, air-conditioner can the mode of leaving home move for example about 1 hour, to replace continuous dehumidifying.

When temperature is lower than design temperature, stop the dehumidifying operation, to realize saving the operation of the energy.Since be unmanned room to be carried out air conditioning in this mode of leaving home, the situation that this can exist room temperature to reduce, thus can cause effect on moisture extraction to worsen.Therefore, when being lower than 10 ℃, temperature interrupts operation of air conditioner, to reach energy-conserving action.

Explain the dewfall mode that suppresses now.When room temperature reduced after stopping with the mode of heating operation in the winter time, unnecessary moisture can condense into the globule on indoor window and wall.Stop before sleeping after the heating operation, the operation that dehumidifies in the predetermined time cycle, so that suppress dewfall, Here it is suppresses the dewfall mode.When selecting to suppress the dewfall mode by flicking dehumidifying button 14, air-conditioner does not only carry out temperature control with the dehumidification mode operation.Air-conditioner moves two hours continuously with standard mode, and indoor humidity is reduced as far as possible.When presetting, select low wind speed.Running time can be prolonged by handling timer button 16.It should be noted that, when room temperature is lower than 10 ℃, interrupt this inhibition dewfall mode.

When air-conditioner moved to suppress the dewfall mode, owing to be heating operation season, the heat radiation of outdoor condenser strengthened, and the indoor heat that adds reduces, thereby caused indoor temperature to descend, and therefore, when room temperature is lower than 10 ℃, stopped the operation of air-conditioner.

Because the moisture in the outdoor cold air cooling chamber, so morning in the winter time on the glass pane dewfall phenomenon can take place.Therefore, if suppress indoor humidity, just can suppress the dewfall phenomenon.Suppressing the dewfall mode is exactly in order to reduce indoor humidity, so just can suppress the condensation that takes place second day morning on glass pane, thereby and can prevent that the damage in furniture and house from also can suppress the breeding of flat lice and mould.

Figure 21 diagramming goes out air-conditioner and is suppressing dewfall operation beginning back earlier with mode of heating operation 6 hours required experimental data (being represented by solid line) when suppressing the dewfall mode and move 2 hours again, with the air-conditioner result that required data are compared under with regard to situation out of service after with the mode of heating operation.These experimental datas are to measure at the center in house with near the place of window.At this moment experiment condition is as follows: Western-style house is of a size of 3.6m * 3.6m, and unmanned in the room, outdoor temperature is 1 ℃, and outside relative humidity is 80%, and room temperature is 23 ℃ when air-conditioner moves, and indoor humidity is 60%.

Air-conditioner stops the dehumidifying operation after having moved 2 hours with dehumidification mode of operation after the starting, be reduced to about 13% after near the relative humidity the glass pane reduces to about 20%, 6 hour.Obviously, this inhibition dewfall mode can suppress the dewfall phenomenon that occur second day morning effectively.

Preamble describes in detail, according to the present invention, can suitably select multiple dehumidification mode of operation, and can select to carry out the mutually different dehumidifying operation of content.

As for these dehumidification mode of operation, at least can be according to the needs of life together with setting up temperature, wind speed and running time four kinds of dehumidification modes, i.e. " standard mode ", " laundry drying mode ", " mode of leaving home " and " inhibition dewfall mode ".Thereby improved dehumidification function, make under the relatively poor damp condition of Japan and can obtain a home from home.Also can set up other dehumidification mode of operation if necessary, as balanced way and laundry drying mode-II.

In addition, according to the present invention, only pass through to handle a dehumidification mode of operation button, thereby have good operating characteristics with regard to optional majority kind dehumidification mode of operation.In addition, owing to the content of the dehumidification mode of operation selected can be shown, thereby being easy to judge that whether current dehumidification mode of operation is not to use the required mode of person, this has brought the simplification of operation.

And, according to the present invention, owing to set best primary condition for each dehumidification mode of operation, thereby can save the operation that comparatively bothers when setting service condition by the user.In addition, can change running time arbitrarily by handling the timer button as primary condition.
