DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device used for combustion equipment such as a water heater and a heating boiler.

[0002]

2. Description of the Related Art Conventionally, in a remote control device used for combustion equipment such as a water heater or a heating boiler of this kind,
For example, as disclosed in Japanese Patent Application Laid-Open No. 2000-346443, a setting value changed by operating a setting change unit is notified by voice, so that it can be operated only by groping with a blind person or a shampoo. Even people in the state changed the settings with peace of mind so that hot water could be used comfortably.

[0003]

However, in this conventional apparatus, since there is no time margin between the setting change and the voice notification, after the setting is changed once by the setting change means, the set value is notified by voice. Even if the user notices an error before returning to the original state in a hurry, the user is informed of the sound, and is difficult to use, lacks reliability, and cannot be used with confidence.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention pays attention to this point, and in particular, its configuration is notified of setting change means for changing settings such as temperature, and that the setting has been changed. Voice data storage unit 49 storing the content in voice
And a speaker 34, and a sound output control unit 33 for outputting the sound data of the sound data storage unit 49 to the speaker 34, wherein the remote control device 28 guides the setting change by the setting changing unit by sound. An operation determining unit that determines whether the setting change unit has been operated, a first storage unit 45 that stores a setting value before the start of operation based on an operation start detection signal of the operation determination unit, Each time the operation is performed, a setting timer 46 that is initialized and counts a predetermined non-operation time, a second storage unit 47 that stores a current setting value by counting up the setting timer 46, and the first storage unit 45 And the second storage unit 47
And comparing means 48 for comparing the stored setting values with each other. Only when there is a difference in the comparison of the setting values by the comparing means 48, the audio guidance of the setting change is performed, so that The audio guidance is provided only when the setting is changed, and it is extremely convenient to use.

If the difference is greater than a predetermined value in the comparison of the set values by the comparing means, if the content of the voice guide is changed, it is possible to call attention to the fact that the setting has been largely changed. is there.

A hot water switch 39 for setting a set amount, a plurality of time setting switches 40 for setting a current time and a timer time, and a plurality of temperature setting switches 41 for changing a set temperature of hot water are provided. It is.

The temperature setting switch 41 constitutes a setting change means, and sets the hot water supply set temperature to a high temperature.
Up switch 41a that changes every degree or several degrees
And a down switch 41b for changing the hot water supply set temperature to a low temperature once or several degrees at a time.

The remote controller 28 has an operation discriminator 4 for discriminating whether the temperature setting switch 41 has been operated.

To send to.

The voice output control unit 33 is composed of a voice synthesizing IC, and separate voices for notifying that the set temperature has been changed corresponding to the two types of output signals corresponding to the difference from the comparing means 48. When the difference is not greater than 60 ° C., a voice guide saying “the hot water supply temperature has been changed” is provided. When the temperature is higher than ℃, a voice guide saying "Hot hot water" is given.

Further, the sound output control section 33 outputs an operation confirmation sound "pip" when the operation switch is pressed.

Next, the operation of the embodiment of the present invention will be described with reference to the flowchart shown in FIG. Now, when either the up switch 41a or the down switch 41b of the temperature setting switch 41 is pressed, first, step 5
0, the first storage unit 4
5 stores the hot water supply temperature setting T before the operation.

Next, the process proceeds to step 51, where the hot water temperature setting is changed, that is, the hot water temperature display displayed on the dot matrix type display 31 is added or subtracted once, and a dial tone "bit" is emitted to confirm acceptance. And setting timer 4
6 starts counting for one second.

The program proceeds to step 52 to determine whether or not the temperature setting switch 41 is operated again. If YES, the program proceeds to step 53 to further change the hot water supply temperature setting and the beep sound "bit" and count the setting timer 46. Is cleared, and then the counting is started again.

If NO, the flow advances to step 54 to wait for the setting timer 46 to count up for one second. YES, that is, the count-up for one second is determined to be the end of the setting change operation, the flow advances to step 55, and the second storage The section 47 stores the current hot water supply temperature setting K.

Then, the process proceeds to a step 56, wherein the comparing means 48 determines whether there is a difference between the set temperature T stored in the first storage section 45 and the set temperature K stored in the second storage section 47. == ”, and if YES, that is, if the setting has not been changed, the voice guidance is not performed and the process ends in step 57. If the setting is incorrectly changed once and then restored immediately, the voice guidance is not performed. It is.

If they are not the same, the process proceeds to step 58 if NO, and the set temperature K after the change is
Judges whether it is 0 ° C or more, NO if it is not 60 ° C or more
Then, the process proceeds to step 59, in which the audio output control unit 33 outputs audio data of contents informing that the setting has been changed,
An audio guide of “Hot water temperature has been changed” is provided from the speaker 34 via the amplifier 35.

If the temperature is higher than 60 ° C., the process proceeds to step 60, and a voice guidance for alerting “Hot hot water comes out” is performed in the same manner. After that, the set hot water supply temperature is determined. This data is transmitted to the communication control unit 23
The hot water supply is sent to the main body side control device 2 via a and 23b, and the hot water supply is controlled in accordance with the temperature.

Therefore, after the setting change is confirmed once, the user is notified of the change of the setting by the voice guide only when the change is surely made, so that there is no erroneous notification due to erroneous operation. It is accurate, reliable and can be used with peace of mind. If the temperature is higher than 60 ° C, it will be guided by a different voice guide that it is dangerous at high temperature. Can be done.

In this embodiment, the hot water supply temperature setting has been described as an example. However, the present invention is not limited to this, and it goes without saying that, for example, bath temperature setting or bath hot water amount setting may be used.

[0028]

As described above, according to the present invention, the setting value before the setting change is compared with the setting value after the setting change, and voice guidance is performed only when there is a difference, so that the setting can be surely performed. When the setting is changed by mistake and the setting is changed back in a hurry as in the prior art, the voice guidance is not performed, and the device is easy to use, reliable, and can be used with peace of mind.

Further, when there is a difference larger than a predetermined value, by changing to a voice guide for calling attention, it is possible to easily avoid a dangerous state and use the apparatus with peace of mind.
