Description
The present invention relates to have the alarm device of the household electrical appliance of hummer for carrying out the regulation alarm relevant action with content of operation or movement content etc.
In the past, in these class household electrical appliance such as micro-wave oven, electric cooker, washing machine, mainly the buzz with piezoelectric buzzer carried out it is keyed in the alarm action of content of operation or the alarm action of release etc.Specifically, for example in the micro-wave oven that has open type grill function, be provided with the auto-excitation type piezoelectric buzzer of under alive state, ringing with the vibration frequency of 2KHz, and operation or operating state corresponding to micro-wave oven, make above-mentioned piezoelectric buzzer move (connection), as an example, its action following (" disconnection " is the action stopping period).
The key input validation ... the each connection 0.15 second;
End of cooking alarm signal ... 0.5 second connection disconnected in/0.5 second, carried out repeatedly 3 times;
The alarm signal of cooking (preheating during the open type cooking finishes alarm signal etc.) ... 0.5 second connection disconnected in/0.5 second, carried out repeatedly 5 times;
Fault alarm ... 0.15 second connection disconnected in/0.15 second, carried out repeatedly 7 times;
User's faulty operation ... 0.15 second connection disconnected in/0.15 second, carried out repeatedly 7 times.
Under above-mentioned various situations, the sound pressure level (size of sound) of the signal sound during the piezoelectric buzzer action keeps certain, is continuant.In addition, as required, be provided with the device of conditioning signal sound size, even but when carrying out this adjusting, above-mentioned signal sound remains the continuant of certain sound pressure level.
Except micro-wave oven, at other household electrical appliance for example in electric cooker or the washing machine etc., the piezoelectric buzzer about using vibration frequency as 2KHz usually carries out the alarm action.Therefore, as in the past, keep certain sound pressure level to be under the continuant state in the signal sound of sending by piezoelectric buzzer, the user is when confirming above-mentioned signal sound, be difficult in many cases judge this signal sound from which household electrical appliance is sent, very inconvenient in actual use.
And in structure in the past, the content of multiple alarm action is distinguished by the perseveration number of times of the piezoelectric buzzer of the dull sound that sends certain frequency and certain sound pressure level or the length of actuation time, therefore, the user is difficult to distinguish various alarm content as described above really, from this respect, very inconvenient in actual use.
In addition,, do not have the key element of the naturetone of the fluctuating of sound or decay fully, a kind ofly give artificial and sound stiff sense so must become because signal sound is the continuant of a kind of certain frequency and certain sound pressure level.Therefore, some people often feels ear-piercing to above-mentioned signal sound, and this probably is to hinder the reason that this series products of household electrical appliance is had the high-quality sense.
The present invention In view of the foregoing develops, and its objective is that providing a kind of can discern the alarm content of being sent by hummer clearly.The alarm device that has the household electrical appliance that can as far as possible prevent effects such as the signal sound of being sent by this hummer is ear-piercing simultaneously.
In order to achieve the above object, the present invention is provided with the alarm control device in the household electrical appliance that have hummer for the alarm action of stipulating, when above-mentioned hummer moves, by making the voltage that is added on this hummer, thereby the sound pressure level of signal sound is changed in time at the appointed time by predefined patterns of change.
At this moment can adopt such structure, the vibration frequency that is about to above-mentioned hummer is set in the scope of 0.5KHz～6KHz, makes information that above-mentioned alarm control device will represent magnitude of voltage that hummer is applied be changed to new information successively by 0.1 millisecond～50 milliseconds time range simultaneously.
Above-mentioned alarm control device can make above-mentioned hummer carry out the alarm action at least when the household electrical appliance end-of-job.
The alarm control device also can adopt such structure, and promptly along with the situation of carrying out of household electric appliance operation is carried out multiple alarm action, the while makes the change in voltage pattern difference that hummer is applied along with the difference of the kind of these alarms actions.
The alarm control device can constitute like this, that is, make the time dependent action of sound pressure level of the signal sound of being sent by hummer be separated by the repetition of specified action interval for several times.
At this moment, the following formation of alarm control device gets final product, promptly along with the situation of carrying out of home electric work is carried out the action of multiple alarm, simultaneously along with the difference of these alarms action kinds, make during the action of hummer with pause in action during time length ratio different.
The alarm control device also can constitute like this, promptly when by the emergency of hummer alarm content when high, during the action of control hummer than growing during the pause in action of this hummer.
The alarm control device also can constitute like this, and is promptly when by the emergency of hummer alarm content when high, long actuation time than the alarm of other occasion during the action of control hummer.
The alarm control device also can constitute like this, promptly when the household electrical appliance end-of-job carries out the alarm action by hummer constantly, the time dependent action of sound pressure level of the signal sound that this hummer the sends specified action interval of being separated by is carried out repeatedly repeatedly, control simultaneously during the last action than long during other action.
In device of the present invention, when the alarm of being stipulated by hummer in household electrical appliance moves, the alarm control device makes the sound pressure level time to time change of signal sound by making the voltage that this hummer is applied at the appointed time by predefined patterns of change.Consequently can easily above-mentioned sort signal sound be differentiated with the continuant that keeps certain sound pressure level, can discern this alarm content clearly.In addition, contain the fluctuating that is similar to naturetone or the sound of decay, can prevent as far as possible that therefore this signal sound from making the user feel that ear-piercing situation takes place owing to above-mentioned signal sound can be along with the difference of the set condition of the time changing pattern of sound pressure level.
Because the vibration frequency of hummer is set on arbitrary frequency in 0.5KHz～6KHz scope, so can prevent because of above-mentioned vibration frequency is set to such an extent that cause the maximization of hummer less than 0.5KHz, can prevent from simultaneously to be set to such an extent that cause the unpleasant to hear situation of signal sound to take place greater than 6KHz because of vibration frequency.In addition, at this moment because the voltage that above-mentioned alarm control device will apply hummer is varied to the new information that applies voltage of expression successively by 0.1 millisecond～50 milliseconds time range, so needn't worry to surpass 50 milliseconds and elongates the signal sound that acoustic conductance causes and become dull, can prevent trouble before it happens because of sound pressure level changes the used data volume increase of 0.1 millisecond of generation signal sound that causes of deficiency of time before simultaneously because of the time of sound pressure level before changing.
At least when the household electrical appliance end-of-job, the alarm control device makes the sound pressure level time to time change of the signal sound of being sent by above-mentioned hummer carry out the alarm action, thereby the user can discern the knocking-off time of household electrical appliance clearly.
The situation of carrying out according to household electric appliance operation, the alarm control device changes the sound pressure level of the signal sound of being sent by hummer in time and carries out multiple alarm action, simultaneously, at this moment along with the difference of above-mentioned alarm action kind, make the change in voltage pattern difference that hummer is applied, thereby the user can judge the kind of above-mentioned each alarm action clearly.
The alarm control device repeats repeatedly the time dependent action of the sound pressure level of the signal sound of being sent by the hummer specified action interval of being separated by, thereby can increase the kind of signal sound, so that carry out the alarm of multiple movement content.In addition, send signal sound easily, so can confirm the alarm content clearly with feature.Here be meant certainly during the said pause in action on the hummer not alive during, even wherein also comprise under the state that applies voltage on the hummer, during the state of the sound pressure level of signal sound below people's ear can audible minimum level.
The alarm control device changes the sound pressure level of the signal sound of being sent by hummer in time, and according to the situation of carrying out of household electric appliance operation, carry out multiple alarm action, while is according to the difference of the kind of these alarms actions, change during the action of hummer and the time length ratio during the pause in action, send the signal sound with feature easilier, even when setting multiple alarm content, the user also can easily distinguish these alarm contents.
When the emergency of the alarm content of being sent by hummer is high, the alarm control device makes the sound pressure level time to time change on one side, controlling on one side hummer makes during its action than growing during the pause in action of this hummer, thereby the user can know the alarm content that the emergency of the action of following above-mentioned this hummer is high really, is useful in practicality.
When the emergency of the alarm content of being sent by hummer is high, the alarm control device makes the sound pressure level time to time change on one side, controlling on one side hummer, to make its actuation time longer than the time of carrying out other alarm and moving, thereby in this case, also can know the high alarm content of emergency of following above-mentioned the sort of hummer action for the user really.
When carrying out the alarm action when the household electrical appliance end-of-job and by hummer, the alarm control device repeats repeatedly the time dependent action of the sound pressure level of the signal sound of being sent by this hummer specified action interval of being separated by, control simultaneously during the last action than long during other action, the user feels that by above-mentioned signal acoustic energy the work of household electrical appliance finishes, has increased the serviceability of alarm action.

Explanation applies the present invention to an embodiment of micro-wave oven with reference to the accompanying drawings.
In Fig. 4 of expression overall appearance, be provided with in the front of the main body cover 2 that has Machine Room of laying magnetron, fan etc. and the cooking room (all not shown among the figure) that is adjacent as the micro-wave oven 1 of household electrical appliance and open and close the door 3 that this cooking room is used, be provided with the display part 5 of usefulness such as the operation board 4 that possesses the keyswitch group and display operation content simultaneously.
Fig. 1 shows the electrical structure of micro-wave oven 1 briefly.In Fig. 1, from control power supply terminal+V
CcThe microcomputer 6 (being equivalent to the alarm control device among the present invention) of power supply reaches the control program of storage in advance according to the read output signal of the sensor groups 7 of establishing from the message from keyboard of operation board 4, the cooking of doing for oneself, carry out the control of the displaying contents of display part 5, and the action control of passing through the above-mentioned magnetron even load of driving circuit 8.
Above-mentioned microcomputer 6 is by D/A change-over circuit 10 control auto-excitation type piezoelectric buzzers 9, when carrying out this control, according to being the apply voltage of the pattern change of foundation to piezoelectric buzzer 9 with the described data set in back that is stored among the data ROM11.Piezoelectric buzzer 9 is configured in for example inboard of operation board 4, and its vibration frequency is set in the setting in 0.5KHz～6KHz scope, for example 2KHz.The clock frequency of microcomputer 6 is set at for example about 4.19MHz.
Expression is added to the voltage in several modes data Δ V (being equivalent to claim 2 described " information of the magnitude of voltage that expression applies hummer " of the present invention) of the time series changing pattern of the voltage on the piezoelectric buzzer 9 to quantize state storage in data ROM11 by D/A change-over circuit 10.At this moment, microcomputer 6 by data pointer (register) in accordance with regulations the cycle specify address among the ROM11 successively, read above-mentioned output voltage data Δ V.The readout interval of above-mentioned output voltage data Δ V is set at the stipulated time in 0.1 millisecond～50 milliseconds scopes, for example 5 milliseconds.Therefore output voltage data Δ V changes into new data successively by the time in 0.1 millisecond～50 milliseconds scopes.
Fig. 5～Fig. 9 shows the pattern example of voltage in several modes data Δ V, below these patterns of explanation.Among Fig. 5～Fig. 9, transverse axis represents that the longitudinal axis is represented the output valve λ (quantized value) of output voltage data Δ V by the address indicated value of the output voltage data Δ V of data pointer indication.The readout interval of the output voltage data Δ V of data pointer indication is set at 5 milliseconds, as mentioned above so each scale " 1 " on the transverse axis is equivalent to 5 milliseconds.
(a) example shown in Figure 5
Fig. 5 is applied to the pattern of the output voltage data Δ V on the piezoelectric buzzer 9 when representing to carry out key entry operation on the operation board 4.In this example, output valve λ begins to increase gradually from moderate level, roughly reaches maximal value after 30 milliseconds, after this maximal value or the value approaching with it is kept 40 milliseconds, slowly descends then, reaches zero level through 100 milliseconds after the beginning that descends.
Therefore, when reading output voltage data Δ V shown in Figure 5 and being added on the piezoelectric buzzer 9, the voltage that this piezoelectric buzzer 9 is applied just at the appointed time in (170 milliseconds) by patterns of change shown in Figure 5, thereby the sound pressure level of the signal sound of being sent by this piezoelectric buzzer 9 just changes in time by above-mentioned pattern.If but the level that the voltage that applies does not acquire a certain degree is when above, piezoelectric buzzer 9 does not vibrate usually, and therefore in fact during the state of output valve λ below specified level (for example about " 40 "), piezoelectric buzzer 9 is output signal sound not.
(b) example shown in Figure 6
Fig. 6 is illustrated in the pattern that is added in the output voltage data Δ V on the piezoelectric buzzer 9 when carrying out alarm in required time in the gastronomical process.In this example, output valve λ is with short cycle increase and decrease, and after its envelope slowly increases, from representing that peaked state slowly descends, after this changing pattern continues 540 milliseconds, at interval during the pause in action of stipulated time (for example 540 milliseconds), will continue 540 milliseconds again with the same changing pattern of above-mentioned changing pattern, and then at interval during 540 milliseconds the pause in action, above-mentioned changing pattern is repeated 3 times continuously.
Therefore, when reading output voltage data Δ V shown in Figure 6 and being added on the piezoelectric buzzer 9, the voltage that this piezoelectric buzzer 9 is applied at the appointed time in (3.78 seconds) according to during the action that makes as shown in Figure 6 and the patterns of change that repeats during the pause in action, so the sound pressure level of the signal sound of being sent by this piezoelectric buzzer 9 just changes in time by above-mentioned pattern.Even but in this case, in fact when the state of output valve λ below specified level (for example about " 40 "), piezoelectric buzzer is output signal sound not.
(c) example shown in Figure 7
Fig. 7 is added in the pattern of the output voltage data Δ V on the piezoelectric buzzer 9 when representing to carry out the fault alarm of micro-wave oven 1.In this example, output valve λ is during through 510 milliseconds, and the patterns of change according to begin to carry out to return after " increasing → subtract → increase → subtract " zero level from zero level repeats repeatedly such changing pattern continuously for example 10 times.
Therefore, when reading output voltage data Δ V shown in Figure 7 and being added on the piezoelectric buzzer 9, the voltage that this piezoelectric buzzer 9 is applied just repeats increase and decrease action shown in Figure 7, so the sound pressure level of the signal sound of being sent by this piezoelectric buzzer 9 just changes in time by above-mentioned pattern.Even but in this case, in fact during the state of output valve λ below specified level (for example about " 40 "), piezoelectric buzzer 9 is output signal sound not, thus the time dependent action of the sound pressure level of the signal sound of sending by piezoelectric buzzer 9 at interval specified action interval (above-mentioned output valve λ below about " 40 " during) carry out repeatedly.
(d) example shown in Figure 8
Be added in the pattern of the output voltage data Δ V on the piezoelectric buzzer 9 during warning when Fig. 8 represents to carry out micro-wave oven 1 wrong the use.In this example, output valve λ is during through 500 milliseconds, according to beginning from zero level to carry out to return after " increasing → subtract → increase → subtract " after the patterns of change of zero level, at interval during the pause in action of stipulated time (for example 250 milliseconds), make again and be separated by with the same changing pattern of above-mentioned changing pattern that (250 milliseconds) carry out repeatedly for example 7 times repeatedly during the pause in action.
Therefore, when reading output voltage data Δ V shown in Figure 8 and being added on the piezoelectric buzzer 9, the action that the voltage that this piezoelectric buzzer 9 is applied increases and decreases as shown in Figure 8, the spacing movement interval carries out repeatedly repeatedly, so the sound pressure level of the signal sound of being sent by this piezoelectric buzzer 9 just changes in time by above-mentioned pattern.Even but in this case, in fact during the state of output valve λ below specified level (for example about " 40 "), piezoelectric buzzer 9 is output signal sound not.Therefore, in this case, piezoelectric buzzer 9 is the length during than the fault alarm shown in above-mentioned (c) during the pause in action of output signal sound not.
(e) example shown in Figure 9
Fig. 9 is added in the pattern of the output voltage data Δ V on the piezoelectric buzzer 9 when representing to carry out end of cooking alarm (end-of-job circular).In this example, output valve λ is with short cycle increase and decrease, and after its envelope slowly increases, from representing that peaked state begins to descend gradually, after this changing pattern continues 480 milliseconds, at interval during the pause in action of stipulated time (for example 480 milliseconds), make again with the same changing pattern of above-mentioned changing pattern and continue 480 milliseconds, again through after during 480 milliseconds the pause in action, to increase and decrease than the short period, and after its envelope slowly increases, begin slowly to descend from representing peaked state, this changing pattern continues 1.12 seconds.
Therefore, when reading output voltage data Δ V shown in Figure 9 and being added on the piezoelectric buzzer 9, the voltage that is added on this piezoelectric buzzer 9 is pressed during the action shown in Figure 9 and alternately repeated patterns of change during the pause in action in (3.04 seconds) just at the appointed time, the sound pressure level of the signal sound that this piezoelectric buzzer 9 sends changes shown in above-mentioned pattern in time, and (the 1st time, the 2nd time) was long during (the 3rd time) moved than other during the particularly last action.Even but in this case, in fact when the state of output valve λ below specified level (for example about " 40 "), piezoelectric buzzer 9 does not send signal sound.
Secondly, Fig. 2 and Fig. 3 show the control content of being undertaken by microcomputer 6 briefly, the below relative action of explanation.
Fig. 2 represents the content of master routine, and Fig. 3 represents by the cycle to be the content of the signal sound written-out program that carries out of the Interrupt Process of 5 milliseconds (being equivalent to from the cycle of above-mentioned data ROM11 read-out voltage data Δ V).
In Fig. 2, behind the power connection, carry out the initial setting steps A 1 of the regulation original state of setting display part 5 grades, carry out then the address indicated value of data pointer is arranged to the steps A 2 of initial value for " 1 ", after this judge whether to have carried out to key in operation (steps A 3) according to the signal of keying in from operation board 4.
If carried out keying in operation, then carry out the content of operation of handling (setting of gastronomical process and cancellation, the cooking begin etc. processing) according to the content of this key entry operation and carry out handling procedure A4, carry out the steps A 5 of the data specified sign Fa be provided for indicating piezoelectric buzzer 9 actions then, transfer to the cooking of judging micro-wave oven 1 then and whether move ongoing steps A 6.The sign Fa that is provided with in above-mentioned steps A5 makes the sign of piezoelectric buzzer 9 by output voltage data Δ V action usefulness shown in Figure 5.
If when in above-mentioned steps A3, predicating "No", when just also not keying in operation, carry out above-mentioned determining step A6, if when in this steps A 6, predicating "Yes", carry out cooking handling procedure A7, proceed to carry out the cooking of setting content among the handling procedure A4 in the aforesaid operations content.After this, judge whether the above-mentioned cooking finishes (steps A 8),, then judge whether it is the needed time of alarm (steps A 9) of being undertaken by piezoelectric buzzer 9 in the gastronomical process if do not finish.
If during needed time of the alarm that is undertaken by piezoelectric buzzer 9 in the gastronomical process, carry out the steps A 10 of the data specified sign Fb that is provided for specifying piezoelectric buzzer 9 actions, return above-mentioned determining step A3 then.The sign Fb that is provided with in above-mentioned steps A10 is the sign that makes piezoelectric buzzer 9 action usefulness with output voltage data Δ V shown in Figure 6.
If when in above-mentioned steps A8, predicating "Yes", just during end of cooking, carry out the steps A 11 of the data specified sign Fc that is provided for indicating piezoelectric buzzer 9 actions, return above-mentioned determining step A3 then.The sign Fc that is provided with in above-mentioned steps A11 is the sign that makes piezoelectric buzzer 9 action usefulness with output voltage data Δ V shown in Figure 9.
On the other hand, if when in steps A 6 and A9, predicating "No", then judge whether in micro-wave oven, to have taken place fault (steps A 12),, then carry out the exception handles A13 that fault is handled action and shown if conclude when fault has taken place by predefined self-diagnosis system.After this, carry out the steps A 14 of the data specified sign Fd be provided for indicating piezoelectric buzzer 9 actions, return above-mentioned determining step A3 then.The sign Fd that is provided with in steps A 14 is the sign that makes piezoelectric buzzer 9 action usefulness with output voltage data Δ V shown in Figure 7.
If when in steps A 12, predicating "No", just conclude when not breaking down, then judge whether to have used mistakenly micro-wave oven 1 (steps A 15), if when predicating maloperation, the maloperation handling procedure A16 that then carries out the action that maloperation is taken measures and show.After this, carry out the steps A 17 of the data specified sign Fe be provided for indicating piezoelectric buzzer 9 actions, return above-mentioned determining step A3 then.The sign Fe that is provided with in steps A 17 is the sign that makes piezoelectric buzzer 9 action usefulness with output voltage data Δ V shown in Figure 8.

When carrying out the alarm action by piezoelectric buzzer 9, according among the data ROM11 in advance the output voltage data Δ V of storage (with reference to Fig. 5～Fig. 9), make the voltage that is added on this piezoelectric buzzer 9 according to predetermined at the appointed time patterns of change, thereby the sound pressure level of signal sound is changed in time, therefore can easily distinguish signal sound as described above and continue the continuant passed with certain sound pressure level, the user can discern its alarm content clearly.In addition, above-mentioned signal sound according to sound pressure level in time changing pattern set condition and can contain sound (for example Fig. 5, Fig. 6, Fig. 9) near the fluctuating or the decay of naturetone, can do one's utmost therefore to prevent that this signal sound from making the user feel that ear-piercing situation takes place.
When signal sound being set in less than 0.5KHz, the maximization of piezoelectric buzzer 9 is inevitable, in addition, if when being set in signal sound greater than 6KHz, especially concerning the elderly, cause the unpleasant to hear result of signal sound inevitably, but in the present embodiment, the vibration frequency of piezoelectric buzzer 9 is set in arbitrary frequency in 0.5KHz～6KHz scope, therefore can prevents the maximization of this piezoelectric buzzer 9, can prevent that the unpleasant to hear situation of signal sound from taking place simultaneously.
Be set in the stipulated time in 0.1 millisecond～50 milliseconds the scope from the readout interval of the voltage data Δ V of data ROM11 output, for example be 5 milliseconds, so the time before sound pressure level changes with the output voltage data Δ V that reads can be above 50 milliseconds, thereby needn't worry that signal sound can prolong monotonously and becomes dull with sound pressure level, can also prevent simultaneously since the time of sound pressure level before changing less than 0.1 millisecond of data volume increase that makes output voltage data Δ V.
During the end of cooking that undertaken by micro-wave oven 1, the sound pressure level of the signal sound of being sent by piezoelectric buzzer 9 changes in time and carries out the alarm action, so the user can confirm the cooking end time of micro-wave oven 1.Particularly when carrying out such end of cooking alarm, the time dependent action of the sound pressure level of the signal sound that piezoelectric buzzer 9 sends is according to output voltage data Δ V shown in Figure 9, the specified action interval repeats 3 times at interval, during the simultaneously last action than growing during other action, so the user knows that according to sort signal acoustic energy the work of household electrical appliance finishes, increased the serviceability of alarm action.
The time dependent alarm action of the sound pressure level of the signal sound that piezoelectric buzzer 9 sends is carried out polytype alarm according to the situation of carrying out of the cooking action of micro-wave oven 1, while is corresponding to the kind of above-mentioned various alarms actions, the pattern that is added in the variation of the voltage on the piezoelectric buzzer 9 also has nothing in common with each other, so the user can judge the kind of above-mentioned multiple alarm action reliably.
The time dependent action of the sound pressure level of the signal sound that piezoelectric buzzer 9 sends, alarm in carrying out gastronomical process, when fault alarm, wrong way alarm and end of cooking alarm, according to Fig. 6～output voltage data Δ V shown in Figure 9, the specified action of being separated by interval repeats repeatedly.Therefore can increase the kind of signal sound, carry out the alarm of multiple movement content, can more easily show the feature of signal sound simultaneously, can more clearly confirm the alarm content.
In this case, specifically, the kind of the alarm of piezoelectric buzzer 9 action such as the fault alarm example of Fig. 7 correspondence, and shown in the wrong way alarm example of Fig. 8 correspondence, different during the action of this piezoelectric buzzer 9 with the time scale of moving between stand-down.Therefore, the easier feature that shows signal sound is so even when setting multiple alarm content, the user also can easily distinguish these alarm contents.
As fault alarm, when the emergency of the alarm content of being sent by piezoelectric buzzer 9 is high, shown in the example among Fig. 7, sound pressure level is changed in time on one side, control on one side during the action of piezoelectric buzzer 9 than growing during its pause in action, therefore the user can know the high alarm content of above-mentioned the sort of emergency that piezoelectric buzzer 9 sends conscientiously, is useful in practicality.
When the emergency of the alarm content of sending when piezoelectric buzzer 9 is high, for example during fault alarm, this piezoelectric buzzer 9 is moved continuously, the actuation time of the actuation time of controlling piezoelectric buzzer 9 in other words when carrying out other alarm is long, thereby the user can know the alarm content that the emergency of the action of following piezoelectric buzzer 9 is high conscientiously, and is useful in practicality.
The invention is not restricted to the foregoing description, can carry out expansion as described below or distortion.
Said structure is according to the output voltage data Δ V that stores among the data ROM11, control is added in the voltage on the piezoelectric buzzer 9, but also can adopt following structure, is about to represent that the functional expression of signal sound pattern stores, carry out computing according to this functional expression, control the above-mentioned voltage that applies.Be not limited to micro-wave oven, usually also can be applicable to other household electrical appliance such as electric cooker, washing machine, under this occasion, when even the vibration frequency of the piezoelectric buzzer in the various device is closer to each other, or when using in the various device with a kind of piezoelectric buzzer, also the signal sound with feature can be distributed to each electrical equipment, this is favourable.In addition, also be not limited to piezoelectric buzzer, also can utilize the hummer of other form.
By above explanation as can be known, if employing the present invention, when then carrying out the alarm action by hummer, by making the voltage that is added on this hummer at the appointed time by predefined patterns of change, thereby the sound pressure level of signal sound is changed in time, so the user can confirm the alarm content that above-mentioned hummer sends clearly, can do one's utmost to prevent that the signal sound of this hummer is ear-piercing simultaneously, have useful effect.
In addition, carry out situation and carry out multiple alarm action when adopting corresponding to the work of household electrical appliance, when making simultaneously the different structure of the changing pattern that is added in the voltage on the hummer corresponding to the kind of these alarms actions, the user can differentiate the kind of above-mentioned multiple alarm action effectively, and is useful in practicality.If adopt the time dependent action of sound pressure level make the signal sound that hummer the sends specified action interval of being separated by to carry out repeatedly structure repeatedly in addition, then can realize the further variation of alarm content.
