Furthermore it is also possible to it is envisioned as：Such as food materials supervisory frame is shown after commercial advertisement is shown or is showing business Display image etc. as obtained from shooting in refrigerator camera 15 after advertisement.That is, display part 17 might not be only shown from outer The data that portion receives.

That is, the information exported from display part 17 and loudspeaker 19 includes：As film according to the meaning of user and The information of display and the information shown as the image of TV intercoms independent of the meaning of user that is, when any The information of machine output.In addition, shown image is not limited to animation, can also be still frame.

Next, the effect to above-mentioned composition illustrates.

As described above, in the case of refrigerator 1, when picking and placeing food materials or guidance panel 5 being operated, it is necessary to close to ice The face side of case 1, it is envisaged that image or the listening near loudspeaker 19 can be watched near display part 17 by going out.So Afterwards, in this case, it is possible to cause photosensitivity breaking-out, Hearing etc., user is impacted.On the other hand, such as Fruit is only not show image or do not export the composition such as sound, then can not meet to want to provide information this need to user Ask.

Therefore, the refrigerator 1 of present embodiment can reduce the influence to caused by user as described below, further, it is possible to full Foot is wanted to provide information this demand to user.

First, display part 17, loudspeaker 19 generally have：Adjust image output when brightness, output sound when volume Function.Specifically, the chart of the solid line shown in Fig. 3 for it is usual when i.e. without adjustment export in the state of brightness or The output valve of sound.In addition, in present embodiment, the output valve of so-called brightness refers to the lightness of picture, so-called sound it is defeated Go out value, refer to volume.In addition, refer to when so-called usual：The state or user that brightness, volume have been set when being product export Brightness, the state of volume are reset.

Then, compared with when usual and when reducing brightness or the reduction of volume, shown in dotted line, brightness or sound The output valve of sound than it is usual when it is low.Moreover, if brightness or volume are reduced like this, it is considered that can reduce：To making The possibility that user impacts.In addition, preset the ratio for reducing brightness and volume.

Therefore, refrigerator 1 determines whether to adjust brightness or volume based on condition set in advance.In present embodiment, As the reduction condition for making brightness or volume reduction, it is set as detecting people.More specifically, on present embodiment Reduction condition, is set to：Input to guidance panel 5 that is, when detecting operation, it is door 3 when opening, door 3 when closing, logical Among crossing when proximity transducer 8 detects people at least any one.

Then, (the S1 in the case where performing the processing of the adjustment shown in Fig. 4 and being determined as the establishment of reduction condition of refrigerator 1： YES), perform：With than it is usual when also low state output brightness or the reduction of volume act (S2).That is, refrigerator 1 is reducing In the case that condition is set up, the patterns of change made from display part 17 and the output of loudspeaker 19 is relatively to suppress to user Caused by the side that influences.Thereby, it is possible to suppress the influence to caused by user.Now, although omitting diagram, refrigerator 1 Maintain to make the state that output mode changes in the state of people is detected, on the other hand, if not detecting people, According to the instruction from master control part 9, when the output mode is returned to usual.

But, it is bright as shown in Fig. 3 single dotted broken line when making brightness or the increased increase of volume compared with when usual Degree or sound output valve than it is usual when it is big.If brightness or volume like this is increased, it is considered that exporting When the possibility rise that is impacted to user, can to user but in the case where being the higher information of priority level Influence can be further reduced in result by ground transmission information.In addition, preset the ratio of increase brightness and volume.

Therefore, in present embodiment, as brightness or the increased increase condition of volume is made, being set as should be to user The information of transmission.Such as the disaster information such as rapid earthquake information report, inform concentrating in residential quarter other floors fire occur to carry out prompting Fire remind and inform etc. that information is considered the higher information in priority street, urgency.In addition, the outgoing schedule such as predetermined is also recognized To be the information that notify the relative importance value to user higher.

Therefore, refrigerator 1 is in the adjustment processing shown in Fig. 4, (the S1 in the case where being determined as that increase condition is set up：NO、 S3：YES), perform：With than it is usual when increased state output brightness or the increase of volume action (S4).That is, refrigerator 1 exists In the case that increase condition is set up, the patterns of change made from display part 17 and the output of loudspeaker 19 is easily to be recognized by user Can side.Thereby, it is possible to user's reliably transmission information.Now, although omitting diagram, refrigerator 1 is detecting Maintain to make the state that output mode changes in the state of people, on the other hand, if not detecting people, according to coming from The instruction of master control part 9, when making the output mode return to usual.

Then, as mentioned above, the information exported from display part 17 and loudspeaker 19 includes：It is defeated according to the meaning of user The information and the information in the output of any opportunity gone out.Then, the information on being exported on any opportunity, it is believed that sometimes in door Also exported in the case of nobody before 3.

Therefore, (the S1 in the case where being determined as that reduction condition and increase condition are invalid of refrigerator 1：NO、S3：NO), hold OK：With with it is usual when the identical state output brightness or usual action (S5) of volume.That is, refrigerator 1 reduce condition and In the case that increase condition is invalid, the output mode from display part 17 and loudspeaker 19 will not be made to change.Thus, Even if, also can be to existing people's transmission information near refrigerator 1 not before door 3.

Thus, refrigerator 1 makes the output mode from display part 17 and loudspeaker 19 change.

Embodiment from the description above, following effect can be obtained.

The refrigerator 1 of present embodiment includes：Main body 2；Door 3, the preceding surface opening of 3 pairs of main bodys 2 of this is opened and closed；Display Portion 17 (device for image), the display part 17 (device for image) include image the front-surface side in door 3；(sound fills loudspeaker 19 Put), the sound for the correction of image connection that the loudspeaker 19 (audio unit) output is shown with display part 17；People's test section, people inspection Survey portion on the door 3 front-surface side detected with the presence or absence of people；And AV control units 16 (control unit), (control of AV control units 16 Portion processed) in the case where detecting people by people's test section, become the output mode of display part 17 and loudspeaker 19 and turn to：With not having There is the pattern for detecting that the situation of people is different.Thus, the output mode from display part 17 and loudspeaker 19 changes, can Reduce the influence to caused by user.

Refrigerator 1 makes the output mode of display part 17 and loudspeaker 19 in the case where detecting people by people's test section Change turns to：The side influenceed to caused by user can relatively be suppressed.Thereby, it is possible to avoid in front of door 3 closely The higher image of viewing brightness is closely listening the sound of big volume, so as to reduce the influence to caused by user.

On refrigerator 1, as people's test section, possesses (the operation of guidance panel 5 for the operation that input is carried out to the refrigerator 1 Portion), the output mode of display part 17 and loudspeaker 19 occurs when detecting the input to guidance panel 5 in AV control units 16 Change.Thereby, it is possible to be accurately detected the someone before of door 3, therefore, it is possible to reliably reduce the influence to caused by user.

On refrigerator 1, as people's test section, possesses opening and closing sensor (the opening and closing inspection that on the door 3 open and-shut mode is detected Survey portion), when door 3 opens, display part 17 and the output mode of loudspeaker 19 is changed.Thereby, it is possible to detect exactly Someone before to door 3, therefore, it is possible to reliably reduce the influence to caused by user.

On refrigerator 1, as people's test section, possess the proximity transducer 8 of existing people near detection door 3, passing through When proximity transducer 8 detects people, display part 17 and the output mode of loudspeaker 19 is set to change.Thereby, it is possible to examine exactly The someone before of door 3 is measured, therefore, it is possible to reliably reduce the influence to caused by user.

Refrigerator 1 maintains during people is detected by people's test section：Send out the output mode of display part 17 and loudspeaker 19 The state for changing.In this case, if the state of image output, sound, then keep brightness and volume constant, if There is no the state of image output, sound, then maintain the state without output.If brightness, volume drastically change, it is considered that The attention of user can be caused on the contrary, still, by maintaining output mode, can be suppressed：For example food materials are being picked and placeed into refrigerator 1 Deng when image, volume change suddenly.

Thus, user's notice will not be attracted so that user attentively picks and places food materials, thus, prevents：Because paying attention to shadow Food materials are made to drop accidentally as the change of, volume, additionally it is possible to reduce risk factor.

In this case, although it is contemplated that original brightness, volume by image source, sound source to be acted than reduction when It is lower again, but, also include in the composition for maintaining output mode：It will not also make the brightness of display even if the luminance-reduction in source The composition for changing that is, will not flashing display.In other words, also include by display pattern is changed and It is not considered as the situation of failure.

Refrigerator 1 have received situation about can determine that such as disaster information as the higher information of priority, urgency Under, turn to the output mode change from display part 17 and the output of loudspeaker 19：The side easily approved by user.It is specific and Speech, perform：Make the increased increase action of brightness, volume compared with when usual.Thus, it is possible to think：On such as rapid earthquake information report, Fire, which is reminded, the information such as informs, being informed by reliably carrying out prompting will be far longer than to user come this advantage that promotes to take refuge Bring this shortcoming of harmful effect.Accordingly, with respect to the higher information of the relative importance value that should be notified to user, by making output mould Formula becomes the side for turning to and easily being approved by user, and its result can bring larger benefit to user.

(other embodiment)

In present embodiment, although as shown in figure 3, give make output on the whole in proportion reduce or increased example Son, still, as shown in figure 5, the upper limit of output when can set reduction action, removes the brightness more than the upper limit or sound Amount.Formed even from such a, can also reduce the influence to caused by user.Furthermore it is possible to using：Come with absolute value Reduce or increase, rather than reduction or increased composition in proportion.

In present embodiment, mainly output mode is changed detecting the opportunity of people, give：Detecting To being able to maintain that the example of the output mode to change during people, but it is not limited to this.Such as refrigerator 1 can be：Example Such as, the composition for making output mode change within the stipulated time after detecting people.Now, on the stipulated time, as long as Setting imagination goes out the time that user leaves the front of door 3.

Specifically, can use：After being inputted to guidance panel 5 to during have passed through the stipulated time, Door 3 open after to during have passed through the stipulated time, after door 3 is closed to during have passed through the stipulated time, passing through Proximity transducer 8 is detected after people to the composition for during have passed through the stipulated time, making output mode change.Even if root Form according to such a, can also avoid：Closely watch the higher image of brightness or closely listen the sound of big volume Sound, so as to reduce the influence to caused by user.

In addition, in the case where being guidance panel 5, the detection method inputted to guidance panel 5 is not particularly limited, If contacted with switch on guidance panel 5 etc., you can be considered as in operation, operation can also be set to tie on guidance panel 5 Beam button (operation determines button) etc., in the case where finger leaves Cao Zuoanjian several seconds, you can terminated with being considered as operation, also The language of " operation starts " " operation terminates " can be identified by voice recognition, thereby determines that the beginning and end of operation.Also I.e., it is possible to for detect for the first time to guidance panel 5 carry out input after time, can also to set the stipulated time For detect for the last time to guidance panel 5 carry out input after time, to set the stipulated time.

Refrigerator 1 is detecting image output in the state of people in the case of following opportunitys by people's test section Display and the opportunity of sound, can use makes the composition that image occurs gradually and volume strengthens gradually, that is, it can see at leisure Image, which is waited a moment, slowly improves the composition of volume.If brightness, volume suddenly change, consider that so user can be caused on the contrary Attention, but, by making it occur gradually and strengthening gradually (fade in), can suppress：Image, volume are for example to ice Change suddenly when case 1 picks and places food materials etc..Unexpected image output, sound during thereby, it is possible to suppress people near refrigerator 1, So as to prevent user from getting a fright.

Refrigerator 1 possesses the sound occurring source for sending sound at work, is configured to：In the feelings that sound occurring source is operated Under condition, make the sound increase exported from loudspeaker 19.Refrigerator 1 possesses：Form the compressor 4 of such as cooling body.Pass through compression Machine 4 applies pressure and makes refrigerant circulation, therefore, rotation sound is sent from compressor 4.Therefore, sound is being exported from loudspeaker 19 During, if cooling body works, it is not easy to hear the sound of loudspeaker 19 because of the rotation sound of compressor 4.

Therefore, in the case where compressor 4 works, increased by the sound for making to export from loudspeaker 19, can improved not The situation easily heard.In this case, it is controlled in a manner of increase/reduction seamlessly to carry out volume, Neng Gou The person of being not used by makes volume change in the state of noticing.In addition, as sound occurring source, not only comprising compressor 4, go back Include compressor fan 4a, ice maker etc..

In this case, can use：When people is near refrigerator, although making the volume of loudspeaker 19 reduce, The volume composition bigger than the rotation sound of compressor 4.Thereby, it is possible to realize simultaneously：Influence to people and readily hear.

Refrigerator 1 can use：In the case where exporting sound from loudspeaker 19, make what the working frequency of compressor 4 reduced Form.Thus, the rotation change of tune of compressor 4 is small, can improve the situation for being not easy to hear.

In this case, want in user high it is necessary to improve the speed of compressor 4 when ice is made in the short time Refrigerant circulation is carried out fastly, and therefore, speed increase, rotation sound also increases.Therefore, can be with the rotary frequency of compressor 4 Rate (low speed, middling speed, high speed etc.) accordingly, such as increases 5% volume in low speed, increases 10% volume in middling speed, Constantly increase 20% volume etc. at a high speed, make the increased ratio of volume to adjust.

Refrigerator 1 is configured to：The sound that can perform makes to export from loudspeaker 19 in the case where compressor 4 works increases Big processing and the processing for reducing the working frequency of compressor 4 in the case where exporting sound from loudspeaker 19, and perform pre- The processing first selected by user.

The sensation related to sound, which is all said, to vary with each individual.It is therefore contemplated that the people of sound sensitive can be minded very much Noise (abnormal sound) is mixed with from the sound of loudspeaker 19, on the other hand, it is envisaged that also have what is less minded even if noise is mixed with People.

Therefore, user can be according to respective sensation, to select：Make in the case where compressor 4 works from loudspeaker The processing and reduce the working frequency of compressor 4 in the case where exporting sound from loudspeaker 19 that the sound of 19 outputs increases Processing, thus, turn into and use eaily refrigerator 1.Furthermore it is possible to by the way that " sound sent from loudspeaker 19 will be made Sound, which increases/do not increase ", " make the work sound of compressor 4 reduce/, not to be reduced " combine and be shown in such as guidance panel 5, display part 17 It is first-class, to set selection operation.

Refrigerator 1 is configured to：The sound that can perform makes to export from loudspeaker 19 in the case where compressor 4 works increases Big processing (following, to be referred to as the former processing for convenience) and make compressor 4 in the case where exporting sound from loudspeaker 19 The processing (following, the referred to as processing of the latter for convenience) that reduces of working frequency, had to go to the toilet the situation of quickly cooling but needing refrigerator Under, the processing for the sound increase for making to export from loudspeaker 19 is performed, on the other hand, is had to go to the toilet the situation of quickly cooling but not needing refrigerator Under, execution makes the processing that the working frequency of compressor 4 reduces.

In the case where performing the former processing, although not changing to cooling performance, make to increase volume Power consumption increases.On the other hand, in the case of processing after execution, although can suppress power consumption, cooling performance but has Reduced.Therefore, according to whether rapidly cooling down, automatically to switch the processing of the former processing and the latter.

For example, in the case of outside air temperature higher (25 DEG C with first-class), ice the temperature inside the box according to the opening and closing number of door 3 or The opening time of door 3 and correspondingly risen, therefore, no matter the detection value of temperature sensor 13 whether there is rising in refrigerator, Rapidly cooled down.In addition, indicate guidance panel 5 in user and proceed by ice making function, Quench function, IQF work( In the case of energy, also rapidly cooled down.

Therefore, when execution rapidly cools down, send：The volume for making to export from loudspeaker 19 becomes big instruction, on the other hand, Rapidly cool down when beyond, operate compressor 4 it is usual when, from loudspeaker 19 export sound in the case of, make compressor 4 Speed reduces.Thereby, it is possible to automatically switch the former processing and the latter processing, can carry out corresponding with situation Appropriate work.

Refrigerator 1 can make the change of the output mode of display part 17 and loudspeaker 19 multiple, and preferential change can relatively press down Make the pattern influenceed to caused by user.In the case where carrying out the change of above-mentioned various output modes, for example, in door 3 Opening and closing when, operation to guidance panel 5 when, proximity transducer 8 is when detecting people, then set the preferential of following processing higher Rank, i.e.,：The processing, the processing occur/strengthened gradually gradually and the place for maintaining output mode of brightness and volume reduction will be made Reason, and the processing on making the increased processing of the volume of loudspeaker 19 and reducing the speed of compressor 4, then lower Set their priority level.Hereby it is possible to preferentially carry out reducing the work of the possibility of following situations, i.e.,：To user with The influence that comes, make the situation of its its notice that gets a fright or weaken.

In present embodiment, give：The composition for the instruction for making output mode change is sent from master control part 9, no Cross, can be from master control part 9 by with whether detecting the associated information of people and notifying, to AV control units 16, to determine whether to pass through AV control units 16 make output mode change.Furthermore it is possible to enter to exercise in phase using master control part 9 and AV control units 16 defeated The control that exit pattern changes.

Although multiple embodiments of the present invention are illustrated, these embodiments are to propose as an example , it is not intended to limit the scope of invention.These new embodiments can by it is other it is various in the form of implemented, can be not Various omissions, displacement, change are carried out in the range of the purport of disengaging invention.These embodiments and its deformation are included in invention Among scope and purport, and it is also contained among invention and its equal scope described in claims.
